Summary
Iris prolapse is significantly less common after phacoemulsification cataract surgery compared to extracapsular surgery. Suturing extended scleral sections is crucial to prevent this complication.
Area of Science:
- Ophthalmology
- Surgical Complications
Background:
- Iris prolapse is a known complication following cataract surgery.
- Understanding the incidence and risk factors associated with different cataract extraction techniques is essential for improving patient outcomes.
Purpose of the Study:
- To compare the incidence of iris prolapse after extracapsular cataract extraction (ECCE) versus phacoemulsification.
- To identify specific surgical factors contributing to iris prolapse.
Main Methods:
- Retrospective review of clinical notes for iris prolapse repair cases over 5 years.
- Analysis of 7252 cataract operations, categorizing by ECCE and phacoemulsification.
- Correlation of prolapse occurrence with incision type and scleral tunnel closure.
Main Results:
- Iris prolapse occurred in 93.3% of cases following extracapsular surgery.
- Only 3 cases of phacoemulsification-related prolapse were identified, all associated with unsutured, extended scleral tunnels.
- The average best-corrected visual acuity post-repair was 6/9.
Conclusions:
- Iris prolapse is substantially less frequent after phacoemulsification.
- Suturing of all extended scleral sections is recommended to prevent iris prolapse, regardless of the cataract extraction technique.
