Summary
Epikeratophakia surgery shows promising visual recovery for aphakia patients, with most achieving preoperative acuity. However, complications like astigmatism and reduced contrast sensitivity were noted in this series.
Area of Science:
- Ophthalmology
- Corneal Surgery
Background:
- Epikeratophakia is a refractive surgical procedure involving the implantation of a donor corneal button.
- This study evaluates outcomes in a series of patients undergoing epikeratophakia for various conditions.
Purpose of the Study:
- To assess the visual outcomes and complications of epikeratophakia in a cohort of 67 patients.
- To analyze the effectiveness of epikeratophakia in correcting aphakia and keratoconus.
Main Methods:
- Retrospective review of 67 epikeratophakia cases with an average follow-up of 12.2 months.
- Analysis of visual acuity, refractive outcomes, and complication rates.
Main Results:
- For aphakia, 83% of 57 patients achieved preoperative visual acuity by nine months.
- Refractive correction to within 3 diopters of emmetropia improved from 57% to 75% in the latter part of the series.
- Significant visual outcomes were observed in keratoconus cases (86% achieving 6/9 acuity), with one myopia case achieving desired correction.
Conclusions:
- Epikeratophakia can restore functional vision in aphakic and keratoconic eyes.
- Potential complications include astigmatism and reduced contrast sensitivity, necessitating careful patient selection and management.
