    Trabeculectomy surgery on aphakic eyes showed a low success rate, particularly in younger patients. Success rates significantly increased for patients aged 50 and older, highlighting age as a key factor in surgical outcomes.

    Area of Science:

    • Ophthalmology
    • Glaucoma Surgery
    • Retrospective Clinical Studies

    Background:

    • Aphakic eyes present unique challenges for glaucoma management.
    • Trabeculectomy is a common surgical procedure for reducing intraocular pressure.
    • Previous studies on trabeculectomy outcomes in aphakic eyes are limited.

    Purpose of the Study:

    • To evaluate the long-term success rates of trabeculectomy in aphakic eyes.
    • To identify factors influencing the outcomes of glaucoma surgery in this patient population.

    Main Methods:

    • Retrospective review of 127 trabeculectomies performed on aphakic eyes between 1972 and 1982.
    • Exclusion of 45 cases due to confounding conditions, short follow-up, or prior surgeries.
    • Analysis of 82 remaining cases based on intraocular pressure control and need for further intervention.

    Main Results:

    • Overall success rate was 39% (intraocular pressure ≤21 mmHg with medication or ≤25 mmHg without).
    • Qualified failures accounted for 10% and complete failures for 51%.
    • Success rates were significantly lower in patients younger than 50 (5%) compared to those 50 and older (50%).

    Conclusions:

    • Trabeculectomy in aphakic eyes has a limited success rate, with a high proportion of failures.
    • Patient age is a critical prognostic factor, with older individuals experiencing better surgical outcomes.
    • Further research is needed to explore alternative surgical strategies for aphakic glaucoma.
