Association Between Types of Posterior Staphyloma and Refractive Error After Cataract Surgery for High Myopia

Purpose: To investigate the association between different types of posterior staphyloma (PS) and refractive error (RE) after cataract surgery in patients with high myopia.Methods: This retrospective study included 113 eyes of 113 highly myopic patients with PS. PS was detected using a wide-field fundus imaging system. PS was classified into wide macular, narrow macular, and other types. RE equaled the actual spherical equivalent (SE) minus the targeted SE values 3 months after cataract surgery.Results: The rates of wide macular, narrow macular, and other types of PS were 46.02, 39.82, and 14.16%, respectively. There were no significant differences in best corrected distance visual acuity (BCDVA) or SE among the three classifications of PS before cataract surgery (P> 0.05). However, postoperative BCDVA and SE were significantly different among the three types of PS patients (P

Late in-the-bag intraocular lens (IOL) dislocation is a known complication of cataract surgery, and often occurs several years after uneventful operations. The pathophysiology of this condition is related to weakening of the zonulae.1-3 There are several predisposing conditions, especially pseudoexfoliation syndrome (PEX),2-8 myopia/increased axial length,1,9 previous vitreoretinal surgery,4 trauma,3,4 and uveitis.3,4 Late in-the-bag IOL dislocation was once considered a rare condition, but has increased in frequency in recent decades.

CONCLUSIONS: The study confirmed the advantages of IF pIOL implantation due to rapid visual recovery and stable visual function over the 12-year follow-up and also showed the influence of lower corneal pachymetry regarding EC loss.PMID:34659825 | PMC:PMC8516571 | DOI:10.1155/2021/7027793

This study assessed fall risk in patients with pseudophakic monovision, pseudophakic single vision distance (classic cataract surgery), and cataracts with no surgery.DESIGN: Retrospective single-institution cohort study PARTICIPANTS: Patients with bilateral cataracts diagnosed at 60 years of age or older who underwent bilateral cataract surgery (monovision or single vision distance) or did not undergo any cataract surgery (n = 13 385). Patients with unilateral surgery or a fall prior to cataract diagnosis were excluded.METHODS: Data were obtained from the Stanford Research Repository. Time-to-fall analysis was performed ac...
