Femto-LASIK is a laser eye surgery used to correct refractive errors such as myopia, hyperopia, and astigmatism. It uses a femtosecond laser to create the corneal flap without a mechanical blade, followed by an excimer laser to reshape the cornea. However, the procedure is not suitable for everyone and can cause complications ranging from temporary discomfort to, rarely, serious visual impairment.
Potential complications include dry eyes that may persist, halos, glare, double vision, residual refractive errors requiring further treatment, infection, inflammation, and complications affecting corneal flap healing or position. Rarely, progressive corneal ectasia can cause corneal thinning and distortion, potentially requiring specialized treatment or, in severe cases, a corneal transplant. The likelihood and severity of these complications depend on individual risk factors, including corneal characteristics and pre-existing eye conditions. A comprehensive ophthalmological assessment is essential to determine eligibility and discuss the procedure's benefits, limitations, and alternatives.
