Abstract Details

Purpose:

To present a case of a keratoconic patient who underwent sectorial epithelial removal with transepithelial phototherapeutic keratectomy (t-PTK) (covering the cone only) using high-tech solution laser system followed by corneal collagen cross-linking (CXL) with riboflavin and ultraviolet-A (UVA) irradiation.

Setting:

New Vision Eye Center, Dubai Healthcare City, Dubai, UAE.

Methods:

Clinical case audits series.

Results:

9 eyes with keratoconus underwent CXL treatment after sectorial epithelial removal with t-PTK using a high-tech solution system. No intra- or early postoperative complications were found. One week postoperatively, uncorrected visual acuity (UCVA) improved from 20/63 to 20/32 while best spectacle-corrected visual acuity (BSCVA) improved from 20/40 to 20/25. Corneal topography revealed a significant improvement which remained stable during the six month followup period.

Conclusions:

Sectorial epithelial removal with t-PTK before CXL could improve patients' visual outcome by reducing postoperative high order aberration, postoperative K reading and reducing postoperative pain and rehabilitation period.
