LASEK Laser Eye Surgery
LASEK (Laser-Assisted Sub-Epithelial Keratectomy) is a derivative of PRK whereby the epithelium is loosened with 20% alcohol.
The epitheial cell layer of the cornea is dislodged and put to one side and then replaced after the laser treatment. It has been suggested that LASEK is less painful than PRK and less likely to produce long-term haze. This has not been proven however the procedure is popular, especially in centres on the high street.
Both PRK and LASEK are more painful than LASIK or IntraLASIK, and visual recovery can take a few days to a week, compared to only one day with IntraLASIK.
PRK can be very uncomfortable afterwards. Because of this, many practitioners advocate only performing one eye at a time. LASEK can be performed on both eyes on the same day, however visual recovery takes at least a week and this can compromise return to normal activity.
