Pseudoexfoliation syndrome and extracapsular cataract extraction

Area of Science:

• Ophthalmology
• Surgical Procedures

Background:

• Pseudoexfoliation syndrome is associated with increased ocular risks.
• Cataract extraction is a common procedure, but outcomes in pseudoexfoliation syndrome require careful evaluation.

Purpose of the Study:

• To compare outcomes of extracapsular cataract extraction (ECCE) in eyes with and without pseudoexfoliation syndrome.
• To identify specific challenges and risks associated with ECCE in pseudoexfoliation syndrome.

Main Methods:

• A consecutive case series comparing 139 eyes with pseudoexfoliation syndrome to 762 eyes without.
• Data collected on preoperative findings, surgical procedures, and complications.
• Statistical analysis using a computer program package.

Main Results:

• Patients with pseudoexfoliation syndrome were older (88.5% vs 67.2%, p < 0.001).
• Higher incidence of glaucoma (48.9% vs 6.8%) and poorly dilated pupils (46.8% vs 5.8%) in pseudoexfoliation syndrome eyes.
• Increased risk of capsule/zonulae tears (4.3% vs 1.3%, p < 0.05) but similar vitreous loss.

Conclusions:

• Extracapsular cataract extraction with posterior chamber intraocular lens implantation is a safe procedure for pseudoexfoliation syndrome eyes.
• Careful preoperative assessment and surgical technique are crucial for managing risks like glaucoma and pupil dilation.
• While capsule/zonulae tears are more common, overall complication rates, including vitreous loss, are manageable.
