Cataract
Intraocular lens implantation in the absence of capsular support: a report by the American Academy of Ophthalmology, 2003 ⏩
Meta-analysis
Study question: safety and efficacy of open-loop anterior chamber VS scleral-sutured posterior chamber VS iris-sutured posterior chamber intraocular lenses (IOLs) in eyes with inadequate capsular support. Study result: There is insufficient evidence to demonstrate the superiority of one lens type or fixation site.
Risk of advanced age-related macular degeneration after cataract surgery in the Age-Related Eye Disease Study: AREDS report 25, 2005 ⏩
n=4577, 9.5y
Study question: Post hoc analysis of the AREDS cohort. Does cataract surgery affect risk for AMD progression? Study results: AREDS data suggest that there is no clinically important increased risk of progression to advanced AMD following cataract surgery.
Simple method for accurate alignment in toric phakic and aphakic intraocular lens implantation (2008) ⏩
A technique for the accurate surgical alignment of toric phakic and aphakic intraocular lenses (IOLs) is described in this article and the mathematical relationship between toric misalignment and cylinder error is reviewed: 1 degree of misalignment results in 3.5% of residual cylinder; 3 degrees of misalignment in 10.5% of residual cylinder; and 30 degrees of misalignment in a total loss of the toric’s astigmatic correcting effect.
Vitrectomy Timing for Retained Lens Fragments After Surgery for Age-Related Cataracts: A Systematic Review and Meta-Analysis, 2011 ⏩
n=2380
Study question: Best timing for vitrectomy to recover dropped nucleus parts.
Study results: Best timing is 3-7 days post-op. VA did not differ. Bad prognostic features: low visual acuity, retinal detachment (peri-operative), elevated IOP, intraocular infection/inflammation. 1-week vitrectomy delay increases the probability of a patient's experiencing 1 or more adverse events by 10.3%.
Femtosecond laser-assisted versus phacoemulsification for cataract extraction and intraocular lens implantation: clinical outcomes review, 2018 ⏩
Large studies and meta-analyses of raised capsular complications with FLACS compared with conventional phaco surgery. FLACS does have advantages of a consistent capsulotomy. Equivalence but not superiority of FLACS in terms of VA. FLACS remains 'not' cost-effective. Similar conclusion in the Cochrane review on this issue from 2016.
Abbreviations used on this page:
FLACS - Femtosecond laser assisted cataract surgery
IOP - intra-ocular pressure
Post-op - post operative day
PPV - Pars plana vitrectomy
VA - Visual acuity.
