Capsule-splitting phenomenon during capsulorhexis in pseudoexfoliation

Area of Science:

• Ophthalmology
• Surgical Techniques
• Cataract Surgery

Background:

• Pseudoexfoliation syndrome is a common condition associated with increased risk during cataract surgery.
• Continuous curvilinear capsulorhexis (CCC) is a critical step in cataract extraction with intraocular lens implantation.
• The integrity of the anterior capsule is paramount for a successful CCC.

Observation:

• An unusual tearing pattern of the anterior capsule was observed during CCC in a patient with pseudoexfoliation syndrome.
• The initial capsulorhexis appeared to be composed of pseudoexfoliative material rather than the lens capsule.
• Capsule staining with trypan blue revealed the anterior capsule flap had not folded correctly.

Findings:

• The capsule-splitting phenomenon, where the anterior and posterior leaflets of the capsule separate, was suspected.
• Reinitiating the CCC in the reverse direction successfully completed the procedure without further complications.
• Trypan blue staining effectively identified the capsular defect and guided the surgical correction.

Implications:

• Recognizing the potential for capsule-splitting in pseudoexfoliation syndrome is vital for cataract surgeons.
• Capsule staining is an important adjunct for managing complex CCC in patients with pseudoexfoliation.
• This case highlights the need for adaptability and specific techniques when encountering intraoperative challenges in cataract surgery.
