Objective

To compare the clinical outcome of patients with myopia correction with PRK and LASEK and an amount of correction of -6.0 D MRSE or more.

Methods

67 eyes with a mean preoperative MRSE of -8.5D (-6.0 to -16.0D) were treated with PRK, 29 eyes with a mean preoperative MRSE of -7.5D (-6.0 to -10.5D) were treated with LASEK. Surgery was performed with the Excimer lasers Summit Apex+ (22 eyes PRK), Schwind Keratom MultiScan (27 eyes PRK) and Schwind ESIRIS (18 eyes PRK, 29 eyes LASEK). Preparation of the epithelial flap was done with alcohol 20% and the LASEK-Set of Geuder.

Results

No significant difference could be found between LASEK and PRK if surgery was performed with one of the Schwind Lasers. Neither faster postoperative visual rehabilitation nor reduced amount of haze was observed. Predictability of the refractive effect and postoperative uncorrected/best corrected visual acuity and time until complete reepithelialization were comparable. Corrections with the older Summit Apex+ showed a significant reduced predictability and significant increased corneal haze.

Conclusions

This study found no clinical advantage of alcohol-assisted LASEK over PRK for correction of myopia over -6D MRSE. If alcohol-free (keratome-assisted) LASEK is leading to different results is yet unclear.
