Post-vitrectomy cataract acceleration in phakic eyes: a review

Area of Science:

• Ophthalmology
• Surgical Science

Background:

• Vitrectomy is a standard treatment for posterior segment diseases.
• Post-vitrectomy visual acuity improvement is often followed by cataract formation, necessitating further surgery.
• Nuclear sclerotic cataract (NSC) is the most frequent cataract type observed after vitrectomy.

Purpose of the Study:

• To review current hypotheses on the pathogenesis of post-vitrectomy NSC.
• To discuss known preventive measures against post-vitrectomy NSC.
• To outline treatment options and their associated complications for post-vitrectomy NSC.

Main Methods:

• Literature review of studies on post-vitrectomy NSC.
• Analysis of proposed pathogenetic mechanisms.
• Compilation of data on prevention and treatment strategies.

Main Results:

• The exact pathogenesis of post-vitrectomy NSC remains unclear.
• Several hypotheses exist, but conclusive evidence is lacking.
• Phacoemulsification with intraocular lens implantation is the corrective surgery, carrying risks like longer surgical time and capsular rupture.

Conclusions:

• Understanding the pathophysiology of post-vitrectomy NSC is crucial.
• Preventive strategies are needed to mitigate cataract formation post-vitrectomy.
• Further research is required to elucidate NSC pathogenesis and optimize management.
