Abstract Details

Purpose:

To report the long term results of phototherapeutic keratectomy (PTK) for the treatment of superficial corneal opacities after epidemic keratokonjunctivitis.

Setting:

Beyoglu Eye Training and Research Hospital

Methods:

Thirty-two eyes of 21 patients who were treated with PTK for the superficial corneal opacities induced by epidemic keratokonjunctivitis were retrospectively analyzed. Visual acuity, manifest refraction and high order aberrations were identified for all eyes preoperatively and postoperatively. Corneal topography and anterior segment optical coherence tomography were also evaluated preoperatively and at 12 and 24 months postoperatively. High order aberrations were assessed with the use of a Scheimpflug camera combined with Placido topography. SPSS 22.0 (IBM Corporation, Armonk, NY) software was used to analyze the data

Results:

The mean follow-up period was 26.4 ± 4.0 (23-32) months. The mean age was 24.2 ± 8.4 years. The patients were suffering from the impaired vision related to corneal opacities for 13.2±4.2 (12-18) months. The uncorrected and corrected distance visual acuities were improved at 12 and 24 months postoperatively. The mean postoperative hypermetropic shifts were 0.62 ±0.28 and 0.58±0.35 diopters at 12 and 24 months, respectively. The total higher order, coma, trephoil and spherical aberrations were also decreased significantly after the PTK.

Conclusions:

The long term results demonstrated that PTK is a safe and effective treatment modality for the treatment of superficial corneal opacities after epidemic keratokonjunctivitis. FINANCIAL DISCLOUSRE: NONE
