Abstract Details

Purpose:

The purpose of the study was to evaluate the clinical results of EBK correction of refractive errors.

Setting:

BIEL-MED sp. z o.o., Szpital Pod Bukami , Bielsko-Biała, Poland

Methods:

The material consisted of 47 eyes of 24 patients who had undergone for myopic and hyperopic correction using the EBK procedure that was performed using the Epi-Clear (Orca Surgical, Ashkelon, Israel). This is a dynamic epikeratome - system designed for epithelium removal. Spherical equivalent range: -1.75 to- 8.0D and +1.5 to +4.5D. Surface ablation was followed by excimer laser Allegretto Wave, 400- Hz (Alcon Laboratories, Inc.) in all eyes. Following the procedure, soft bandage contact lenses were placed over the cornea and antibiotic, artificial tears drops, local non-steroid anti-inflammatory agents as well as steroid were applied. The evaluations were performed on the first postoperative day and then in 2, 3 days, 2 weeks and 2 months following the EBK surgery. The comparison of the best postoperative uncorrected visual acuity (UCVA) to the preoperative best-corrected visual acuity (BCVA) with spectacles assessed the efficacy of the method. The corneal reshaping with videokeratography was followed up. The state of the cornea: re-epithialization (with head of 9mm marker-device), subjective symptoms, pain (1-4 levels score) and haze were taken into consideration.

Results:

In all of the cases postoperative UCVA was equal to the preoperative BCVA. The reshaping changes of corneas according to refractive error-removal, by videokeratography were detected. On the 1st or 2nd postoperative day, the patients reported discomfort and pain which was, however, less severe (1st to 2nd level of score) in case of all patients. On the 3nd day, re-epithelialization was complete in all eyes. We did not observe any haze during follow up in any examined patients.

Conclusions:

Among the methods used for correction of refractive errors, EBK is a safe method and more comfortable for patients, which facilitates the healing process, and is characterized by minimum pain sensation. FINANCIAL INTEREST: NONE
