The procedure was completed by phacoemulsification and insertion of an IOL. Disabling glare is often an indication that a cataract has developed. The indications of CTR implantation were zonular dehiscence or weakness associated with mature cataract (29.2 %), trauma (24.3 %), pseudo-exfoliation syndrome (19.5 %), retinitis pigmentosa (14.6 %), degenerative myopia (9.7 %), and lens coloboma (2.4 %). } Insurance makes it easier for patients to cover the overall expense of cataract surgery. Nuclear cataracts are located in the central substance of the lens. Findl O, Drexler W, Menapace R, et al. In a Cochrane review, these investigators evaluated the safety and effectiveness of surgery versus no surgery for post-vitrectomy cataract with respect to VA, quality of life (QOL), and other outcomes. Surv Ophthalmol. Glare was reported less frequently with accommodative lenses but the relative effect of the lenses on glare was uncertain (RR any glare 0.78; 95 % CI: 0.32 to 1.90, 1 study, 40 people, and RR moderate/severe glare 0.45; 95 % CI: 0.04 to 4.60, low quality evidence). Cataract removal surgery is an established surgical procedure with excellent outcomes in improving vision and removing visual impediments. The outcome parameter was the incidence of Nd:YAG laser posterior capsulotomies. The following documentation supporting medical necessity (e.g., office/progress notes, operative note(s)) of the cataract surgery, whether for unilateral disease or bilateral disease (delayed sequential bilateral cataract (DSBCS) surgery or immediately sequential bilateral cataract surgery (ISBCS)) should be available upon request: The Visual Function Index (VF-14),a brief questionnaire designed to measure functional impairment due to cataract, is available here. The authors concluded that the monofocal IOL showed better visual function and lesser photic phenomena than multi-focal IOLs; however patients were spectacle-dependent. Ophthalmology. Cataract removal surgery involving removal of the lens is considered medically necessary without regard to visual disability when any of the following criteria is met: Member has lens-induced disease (e.g., phacomorphic glaucoma, phacolytic glaucoma, phacoanaphylactic endophthalmitis, dislocated or subluxated lens). These researchers used the Science Citation Index to search for references to publications that cited the studies included in the review. 2022 Feb 13 [Online ahead of print]. Neither prediction errors were statistically different between the ORA and IOLMaster alone. There are a number of strategies available to surgeons wishing to exceed these outcomes, the most promising of which are the use of strict-tolerance IOLs and second eye prediction refinement. Accuracy of intraocular lens power calculations using the Zeiss IOL master. At 1 year, trifocal IOL showed no evidence of effect on uncorrected distance VA (MD 0.00, 95 % CI: -0.04 to 0.04; I2 = 0 %; 2 studies, 107 subjects; low-certainty evidence) and uncorrected near VA (MD 0.01, 95 % CI: -0.04 to 0.06; I2 = 0 %; 2 studies, 107 subjects; low-certainty evidence). The studies were at low risk of selection bias, but 2 of the 4 studies did not employ masking and only 1 study included all randomized participants in the final analyses. As an Aetna Vision Preferred member, youre covered for routine eye exams and either one pair of eyeglasses (lenses and frame) or contact lenses or prescription sunglasses. In such cases, diagnostic B-scan ultrasound can accurately image intra-ocular structures and give valuable information on the status of the lens, vitreous, retina, choroid, and sclera. There is inadequate evidence that other pre-operative tests are useful in determining the need for cataract surgery, nor predict the benefits or adverse outcomes from cataract surgery. 1995;21(4):457-460. This condition usually occurs as a part of the aging process, developing on a continuum extending from minimal changes in the crystalline lens to the extreme stage of total opacification. In this series, CTR implant was done in 45 cases. In a Cochrane review, these investigators summarized the effects of different IOLs on visual acuity, other visual outcomes, and quality of life in people with uveitis. Issues in Emerging Health Technologies Issue 85. 1993;5(3):1-5. Statistical analysis was carried out using STATA software v13.1 (StataCorp, Texas); p value of < 0.05 was considered statistically significant. According to Medicare.gov, cataract surgery is considered medically necessary. Most health insurance companies, which cover checkups, prescriptions, and other types of surgery, consider cataract surgery to be medically necessary, and they will cover at least part of the procedure. However, the amount of your cataract surgery that is covered can vary. In a Cochrane review, these investigators defined. Another drawback was only 121 patients out of 289 patients had recorded anterior chamber lengths in chart review. The authors concluded that there was no clear evidence of near acuity improvement despite statistically significant pilocarpine-induced anterior lens displacement. Filkorn and associates (2012) compared IOL power calculation and refractive outcome between patients who underwent laser refractive cataract surgery with a femtosecond laser and those with conventional cataract surgery. The authors concluded that the findings of this systematic review showed that trifocal IOLs provided a better intermediate VA compared with bifocal IOLs, especially for the AT LISA subgroup, while the near and distant visual performance, spectacle independence, CS, post-operative refraction and surgical satisfaction of bifocal IOLs were similar to those of trifocal IOLs. Rathi VM, Sharma S, Das T, Khanna RC. Not much is known if one should also use topical antibiotics after IC injection. After laser pre-treatment, the anterior chamber was stabilized with balanced salt solution during lens and cortex aspiration. Silver Spring, MD: FDA; July 15, 2016. There was no significant difference in the distant-corrected near VA (DCNVA) with MD of 0.04 (95 % CI: - 0.02 to 0.10). Multiple optic (multi-focal) IOLs are available which claim to allow good vision at a range of distances. The immediate surgery group showed mean improvement in best-corrected visual acuity (BCVA) compared with the delayed surgery group at 6 months (mean difference (MD) 0.15 LogMAR, 95 % CI: 0.28 to 0.02). All RCTs comparing a multi-focal IOL of any type with a mono-focal IOL as control were included. The followingare considered medically necessary: Capsular tension rings (e.g., StabilEyes) for stabilization of the lens capsule during IOL placement in conditions associated with weak or partially absent zonules (including primary zonular weakness (e.g., Marfan syndrome), and secondary zonular weakness (e.g., trauma or vitrectomy)); Other medically necessary indications may be cases of zonulysis, pseudo-exfoliation and Marchesanis syndrome. Linebarger EJ, Hardten DR, Shah GK, Lindstrom RL. The use of different IOL types and A-constant modification may have influenced the pre-operative or intra-operative predictions. 2001;21(6):596-601. Thornaval P, Naeser K. Refraction and anterior chamber depth before and after neodynium:YAG laser treatment for posterior capsule opacification in pseudophakic eyes: A prospective study. color: red These investigators concluded that the blue-light filtering AcrySof Natural IOL was equivalent to the conventional AcrySof lens in terms of post-operative visual performance. Comparison of immersion ultrasound biometry and partial coherence interferometry for intraocular lens calculation according to Haigis. Furthermore, this Cochrane review has highlighted the lack of data regarding important measures of the patient experience, such as visual field tests, quality of life measurements, and economic outcomes after surgery, and long-term outcomes (5 years or more). These researchers did not use any date or language restrictions in the electronic searches for trials. 2004;15(1):16-21. are generally excluded by contract; therefore, any IOL implant done for refractive purposes or in conjunction with this type of procedure would not be covered if the surgery itself is not a covered benefit. Of the 1CU eyes, 9 patients (30 %) could read J6 or better at a reading speed of 80 words/min or better. A modified CTR was then inserted and sutured to the ciliary sulcus to center the capsular bag and the IOL was implanted. Zhang Z, Thomas LW, Leu SY, et al. This limited the reliability of the conclusions. background: url('https://www.aetna.com/cpb/medical/data/assets/images/purplearrow.jpg') no-repeat; Aetna does not provide health care services and, therefore, cannot guarantee any results or outcomes. } They used reference lists and the Science Citation Index to search for additional studies. Verhulst E, Vrijghem JC. None of the studies reported the mean change in visual acuity or visual fields. Pediatric cataract surgery following treatment for retinoblastoma: A case series and systematic review. Cost savings were evaluated in 1 study that estimated the costs to be 2.55 times higher in those with pre-operative medical testing compared to those without pre-operative medical testing. The authors concluded that routine use of IC antibiotics may help to reduce the rates of endophthalmitis following MSICS and significantly improved the safety of this effective form of cataract surgery. Dick (2005) stated that the potential clinical benefits of accommodative IOL technology for both cataract patients and refractive patients may place accommodative IOLs in a competitive position with multi-focal IOL technology. 2006;17(1):54-61. Model eye for Nd:YAG laser capsulotomy. In comparison to a highly experienced cataract surgeon, the achieved results in size were similar. li.bullet { 1995;4(4):69-83. It can develop months or years later and is due to a slow growth of epithelial cells remaining from the removed cataract. WebThe response from physicians to Aetnas prior authorization requirement for cataract surgery was overwhelming, and it strengthened efforts to influence the insurer to change its decision. Posterior chamber IOL (PCIOL) was implanted into the capsular bag in all eyes. 2001;27(6):861-867. Two authors independently extracted data and assessed risk of bias for included studies. An IOL is used to improve vision after the native lens is removed by helping to focus light directly onto the retina. Abstracts of Clinical Care Guidelines. 2000;44(6):541. display: none; Neubauer AS, Priglinger S, Ullrich S, et al. In Group A, a CTR was put in the bag before IOL implantation. 2011;(7):CD004242. J Clin Diagn Res. Footnote2*B-scan ultrasound is considered medically necessary in place of A-scan ultrasound where direct visualization of the retina is difficult or impossible including lid problems (e.g., severe edema, partial or total tarsorrhaphy), keratoprosthesis, corneal opacities (e.g., scars, severe edema), hyphema, hypopyon, miosis, dense cataract, pupillary membranes, or vitreous opacities (e.g., hemorrhage, inflammatory debris). Cataracts may be nuclear or posterior subcapsular. Menapace and Dick (2014) noted that the use of femto-second lasers (FSL) surgery improves the precision and reproducibility of corneal incisions and the capsular opening and reduces the amount of ultrasound (US) energy needed for lens nucleus work-up. Interventional Procedure Guidance 209. First, this meta-analysis was not the 1st review that compared the visual performance of patients receiving bifocal or trifocal IOLs implementation; however, this systematic review was the only one that included only RCTs, providing a higher level of evidence. At 6-month follow up, 39 patients had BCVA of greater than or equal to 6/12; IOL decentration was detected in only 3 cases, but without any subjective visual complaints. Biconvex posterior chamber accommodating intraocular lens implantation after cataract surgery: Long-term outcomes. WebFind the best Ophthalmologists covered by Aetna specialised in cataract surgery in Guildford. There was no remarkable increase in IOP or corneal thickness. They found that many patients of low endothelial cell density can be identified through the patient's medical history and clinical examination. This was compared with the earlier rate of endophthalmitis in the same locations. Alternatively, optical coherence biometry can be used in place of A- or B-scan ultrasonography to determine the appropriate pseudophakic power of the IOL. Does Aetna Cover Laser Cataract Surgery You would need to check with your Aetna plan directly to confirm whether coverage of cataract surgery extends to This was of particular relevance against the background of the significantly higher costs. Therefore, it is important that you check the details of the insurance policy before These researchers included RCTs and quasi-randomized trials of eyes affected by both cataract and ARMD in which cataract surgery would be compared to no surgery. This retrospective study included 4,970 eyes of 4,013 cataract patients who underwent phacoemulsification and IOL implantation between January 2000 and January 2008 by the same surgeon at 1 clinic; 4 different IOLs were assessed. In the group without historical data (n = 39), 49 % of eyes were within 0.25 D, 69 % to 74 % of eyes were within 0.50 D, 87 % to 97 % of eyes were within 0.75 D, and 92 % to 97 % of eyes were within 1.00 D of targeted refractive IOL power prediction error. In terms of circularity, the femtosecond laser was superior the manual procedure. The authors concluded that based on the trials identified in this review, there is uncertainty as to which type of IOL provides the best visual and clinical outcomes in people with uveitis undergoing cataract surgery. Policy statement on cataract surgery in the otherwise healthy adult second eye. They contacted study investigators for additional information. Adelaide, Australia: Adelaide Health Technology Assessment (AHTA) on behalf of National Horizon Scanning Unit (HealthPACT and MSAC); 2004. According to Medicare.gov, cataract surgery is considered medically necessary. Femtosecond laser anterior capsulotomy and lens fragmentation was then performed. Cochrane Database Syst Rev. Glasses or visual aids provide satisfactory functional vision; The members lifestyle is not compromised; or. 2001;54(1):23-29. Vanner EA, Stewart MW. In a retrospective consecutive case-series study, Fram and colleagues (2015) compared the accuracy of intra-operative aberrometry technology and the Fourier-domain optical coherence tomography (OCT)-based intra-ocular lens (IOL) formula for IOL power calculation in eyes undergoing cataract surgery after previous laser vision correction (LVC) compared with established methods. These investigators had also hoped to collect data on the type of pathogen involved in endophthalmitis; however, this information was not available. margin-bottom: 38px; Masket S. Preoperative evaluation of the patient with visually significant cataract. Alternatives to routine pre-operative medical testing have been proposed, including self-administered health questionnaires, which could substitute for health provider histories and physical examinations. People in the accommodative lens group were more likely to require laser capsulotomy (Peto OR 7.96; 95 % CI: 2.49 to 25.45, 2 studies, 60 people, 80 eyes, low quality evidence). They last searched the electronic databases on October 3, 2014. Accommodative IOLs have been designed to overcome loss of accommodation after cataract surgery. The change in corneal curvature could also affect the anterior chamber depth and axial length readings, skewing multiple parameters on which ORA bases recommendations for IOL power. Comparison of visual acuity between phacoemulsification and extracapsular cataract extraction: A systematic review and meta-analysis. J Cataract Refract Surg. The Panel concluded that posterior capsulotomy should never be scheduled at the time cataract surgery is performed because one can not predict whether a cataract surgery patient will develop posterior capsular opacification or predict the time at which opacification will occur. 1999;3(5):295-302. Packer M, Fine IH, Hoffman RS, et al. The authors concluded that femtosecond laser could perform a capsulotomy with high reliability. 2010;36(1):34-43. Participating providers are independent contractors in private practice and are neither employees nor agents of Aetna or its affiliates. J AAPOS. All lenses were inserted in the capsular bag, with verification of in-the-bag placement of both haptics. 1993;19(6):675-680. The MAE was 0.37 D for Haigis-L, 0.34 D for ORA, and 0.39 D for Optovue. the extent to which accommodative IOLs improve unaided near visual function, in comparison with mono-focal IOLs; the extent of compromise to unaided distance visual acuity; and. Kletke SN, Mallipatna A, Mireskandari K, et al. Foster CS, Stavrou P, Zafirakis P, et al. There were similar rates in the development of PCO between hydrophobic or hydrophilic acrylic IOLs at 6 months' follow-up (RR 1.00, 95 % CI: 0.80 to 1.25). Graefes Arch Clin Exp Ophthalmol. 2020b;68(11):2451-2455. Primary outcome measure was occurrence of acute clinical endophthalmitis within 6 weeks of surgery. Bower KS. } padding-right: 18px; In Cataract Surgery: Technique, Complications, and Management. The authors concluded that there is low quality evidence that combined cataract and glaucoma surgery may result in better IOP control at 1 year compared with cataract surgery alone. border-width:0; J Cataract Refract Surg. In a Cochrane review, these investigators evaluated the visual effects of multi-focal IOLs in comparison with the current standard treatment of mono-focal lens implantation. Fellow eye comparison between the 1CU accommodative intraocular lens and the Acrysof MA30 monofocal intraocular lens. Available at: http://www.crystalens.com/. These can be either multi-focal lenses, which enable both near and distance vision by virtue of the design of the lens itself, or accommodating lenses, which are intended to move within the eye in a manner similar to a natural human lens. These researchers graded the overall quality of the evidence as low due to observed inconsistency in study results, imprecision in effect estimates, and risks of bias in the included studies. No difference in complications was observed after the initial 100 cases. Visual acuity (best corrected Snellen chart); Visual acuity during glare or contrast sensitivity testing when the best corrected Snellen chart visual acuity is 20/40 or better; Symptomatology; directly related to the presence of the cataract; Physical evidence of the existence of a cataract (e.g., slit lamp examination) and no evidence of other ocular disease (e.g., retinal disease) that would prevent an improvement of vision when the cataract is removed; There is a reasonable expectation that removal of the cataract will improve the patients visual acuity; The use of conservative treatment including current refraction is no longer satisfactory; Degree of functional impairment (This can be in any form; e.g., narrative or assessment tool as long as it supports how the cataract affects the patients ADLs.). } Do DV, Gichuhi S, Vedula SS, Hawkins BS.
