Abstract Details

Purpose:

To investigate visual and refractive results after corneal wavefront guided transepithelial phototherapeutic keratectomy (PTK) for subepithelial infiltrates after adenoviral keratoconjunctivitis.

Setting:

Beyoglu Eye Training and Research Hospital, University of Health Sciences, Istanbul, Turkey.

Methods:

The records of patients who underwent corneal wavefront guided transepithelial PTK for subepithelial infiltrates were retrospectively reviewed. Preoperative and postoperative visual acuity (VA) (Snellen Chart), refractive status and the results of slit-lamp biomicroscopy examinations as well as complications were recorded. The PTK procedure was performed under topical anaesthesia with a Schwind Amaris excimer laser system. Patients' manifest refraction values, topographical examination results, and corneal aberrations before and after surgery were analysed.

Results:

42 eyes of 25 women (59%) and 17 men (41%) were treated. The mean follow-up time was 18.2±6.4 (range: 10-25) months, and the mean maximum ablation depth was 88.6±2.9 (range: 75-110) μm. Postoperative median uncorrected-corrected VA increased from 0.32±0.16 to 0.58±0.16 (P = 0.03). Persistent corneal haze developed in 1 eye of 1 patient, and delayed corneal epithelial healing was observed in 1 eye of 1 patient.

Conclusions:

Corneal wavefront guided transepithelial PTK is an effective and safe method for treating corneal opacities after epidemic keratoconjunctivitis. It provides significant improvement in VA with low complication rate.
