Modified capsulorhexis for fiuid-filled mature cataracts.

Area of Science:

• Ophthalmology
• Surgical Techniques

Background:

• Mature cataracts can develop intralenticular fluid, leading to high intralenticular pressure.
• Existing capsulorhexis techniques may be challenged by fluid-filled, intumescent cataracts.

Purpose of the Study:

• To develop and evaluate a modified capsulorhexis technique for fluid removal in mature cataracts.
• To mitigate the risk of high intralenticular pressure during cataract surgery.

Main Methods:

• Prospective interventional study of 33 eyes with mature cataracts and subcapsular fluid.
• Intravenous mannitol administration preoperatively.
• Modified capsulorhexis involving a novel fluid release and drainage maneuver using a cystotome and spatula, combined with capsule milking.

Main Results:

• The modified technique was successfully applied to 33 eyes.
• Capsulorhexis was completed successfully in all cases, with 94% of cases being easy.
• Minor complications in 2 cases were managed effectively, achieving continuous curvilinear capsulorhexis.

Conclusions:

• The modified capsulorhexis technique facilitates safe and continuous capsulorhexis in fluid-filled mature cataracts.
• The technique effectively manages subcortical fluid, reducing intralenticular pressure.
• Further comparative studies are warranted to validate these preliminary findings.
