Anterior capsule tear after laser iridotomy complicating phacoemulsification

Area of Science:

• Ophthalmology
• Surgical Complications

Background:

• Primary angle closure is a common glaucoma diagnosis.
• Laser peripheral iridotomy (LPI) is a standard treatment for primary angle closure.
• Cataract development is common in patients with a history of LPI.

Purpose of the Study:

• To report a case of anterior capsule rupture during cataract surgery in a patient with prior LPI.
• To highlight the potential risk of LPI-induced anterior capsule defects during phacoemulsification.
• To emphasize the importance of recognizing and managing this complication.

Main Methods:

• A 70-year-old female patient with a history of bilateral LPI underwent cataract surgery.
• Intraoperative anterior capsule rupture was identified at the LPI site.
• Trypan blue staining was used to visualize the capsule defect.
• Capsulorhexis was completed using scissors due to the defect.

Main Results:

• Anterior capsule rupture occurred during cataract surgery at the site of previous LPI.
• Standard continuous curvilinear capsulorhexis was not feasible.
• The cataract surgery was successfully completed using alternative methods.

Conclusions:

• Anterior capsule rupture is a potential, previously unreported complication of LPI during cataract surgery.
• Awareness of this complication is crucial for ophthalmic surgeons.
• Careful intraoperative assessment and tailored surgical techniques are necessary for successful outcomes.
