# What is LASEK eye surgery?

LASEK (laser epithelial keratomileusis) is a surface laser procedure that preserves and replaces the corneal epithelium rather than discarding it, combining features of PRK and LASIK. It is used to correct refractive errors.

## How LASEK Differs

An alcohol solution loosens the epithelium, which is then moved aside as a thin sheet. The excimer laser reshapes the underlying cornea, and the epithelial sheet is repositioned and covered with a bandage lens.

- Aims to reduce discomfort and haze compared with traditional PRK
- No stromal flap is created, preserving more structural strength
- Healing still takes several days with gradual vision improvement
- Some surgeons now prefer transepithelial PRK or other variants instead

## Suitability

LASEK may be considered for patients with thinner corneas, certain occupations, or when flap creation is less desirable. Outcomes are similar to other surface procedures when appropriately selected.

- Pre-operative counselling covers expected recovery time and discomfort
- Regular follow-up monitors epithelial healing and refractive stability
- UV protection after surgery remains important
- Enhancements can usually be performed with repeat surface laser if required
