Nuclear sclerosis after vitrectomy for idiopathic epiretinal membranes

Area of Science:

• Ophthalmology
• Retinal Surgery
• Cataract Research

Background:

• Idiopathic epiretinal membranes causing macular pucker often require surgical intervention.
• Vitrectomy is a common surgical procedure for macular pucker.
• Lens changes after vitrectomy are a significant concern for patients with natural lenses.

Purpose of the Study:

• To investigate the incidence and progression of lens changes, specifically cataracts, following vitrectomy for idiopathic epiretinal membranes in phakic eyes.
• To identify factors associated with the development or worsening of nuclear sclerosis after surgery.

Main Methods:

• Retrospective analysis of 75 consecutive phakic eyes undergoing vitrectomy for idiopathic epiretinal membranes.
• Assessment of lens changes including nuclear sclerosis, anterior subcapsular, and posterior subcapsular cataracts.
• Univariate analysis and Kaplan-Meier life table analysis (including fellow eye comparison) were used.

Main Results:

• 47% of eyes showed the appearance or progression of nuclear sclerosis post-vitrectomy.
• No significant changes were observed in anterior subcapsular cataracts; minimal changes in posterior subcapsular cataracts occurred in 4% of eyes.
• Preoperative nuclear sclerosis, follow-up duration, and surgeon were associated with postoperative nuclear sclerosis. Operated eyes showed significantly more nuclear sclerosis than fellow eyes (P < .0001).

Conclusions:

• Vitrectomy for macular pucker is associated with a high incidence of nuclear sclerosis development or progression in phakic eyes.
• The risk of nuclear sclerosis appears higher in the operated eye compared to the fellow eye, suggesting a potential surgical impact.
• Patient factors (preoperative cataract) and surgical factors (follow-up length, surgeon) influence cataract progression after vitrectomy.
