Abstract Details

Purpose:

To evaluate Trans-Epithelial ablation in patients with post penetrating Keratoplasty Astigmatism.

Setting:

Ambulatory surgery centre (Laser Eye Centre)

Methods:

Incidence of Keratoconus is very high in East Africa. We have been doing PKP for nearly 30 years and post Keratoplasty Astigmatism is a real challenge. In the past, we have tried incisional penetrating keratotomy like; opposite clear cornea (OCCI) incision, the Lasik and Lasek. But now, we are doing Trans-epithelial corneal regularization on the IVIS platform with special software. All the procedures were done under topical anaesthesia and it was based on Tomography regularization.

Results:

26 patients were enrolled and Trans-epithelial corneal regularization was done on Tomography based. Maximum ablation was done about 60-65 microns. Pre-Op and Post-Op Pachymetry, refraction, K-reading, Tomography and high order ablations were noted. Mitomycin .02% was used routinely.

Conclusions:

All patients showed marked improvement of Astigmatism and Corneal regularization. On average there was an Improvement of about 5 diopter of astigmatism. The patient’s refraction can be refracted at procedure. We can prescribe glasses or hybrid contact lenses. There was no sub-epithelial corneal haze and in our opinion this is a very good option relatively non-invasive option for post PKP ablations. FINANCIAL DISCLOSURE?: No
