Risks, Side Effects And Complications Of Lasik Eye Surgery

All medical and surgical procedures have side effects and lasik eye surgery is no exception to this. There are several possible complications and side effects that can occur during and after lasik eye surgery. But, the risks, side effects and complications associated with lasik surgery are much less in compare to other similar eye surgeries. Recovery after lasik eye surgery is very quick, which help in reducing avoiding several complications and side effects.

Several factors have direct and indirect effect on the risks, side effects and complications associated with lasik surgery such as experience and expertise of the ophthalmic surgeon, the general health of the patient, associated medical conditions of the patient (diabetes, hypertension, glaucoma, and immune related diseases), availability of dedicated supportive staffs and care givers, standard of maintenance of equipments etc. With properly selected patients the side effects and complications of lasik eye surgery is minimal.

Intra-operative complication during lasik surgery:

During operation there may be detachment of corneal flap, displacement of flaps or there may remain some particles in the interface of flaps. Displaced flap may need repositioning. Use of latest technology such as “wavefront technology” and IntraLasik and experience of the surgeon can reduce such intra-operative complications to a great extent.

Early postoperative complications of lasik surgery:

Some of the early postoperative complications of lasik are dryness, tearing, diffuse lamellar keratitis (also known as Sands of Sahara Syndrome, as the cornea look like sand bank of a desert), infection and Subconjunctival hemorrhage. Dryness of eye may become persistent and need appropriate management. Diffuse lamellar keratitis is due to presence of WBCs (white blood cells) in between the corneal flap and the cornea, which can be managed with steroid eye drops, but in some cases, may have to remove WBCs manually. Infection can be managed well with antibiotic eye drops.

Late postoperative complications of lasik surgery:

Traumatic flap dislocation may occur even 7 years after lasik surgery. Other late postoperative complications of lasik are epithelial ingrowth, persistence of severe chronic dryness of eye (due to cutting of approximately 70% of nerve fibers of cornea), appearance of glare and halos around bright light at night etc. The late postoperative complications of lasik are rare but the dryness of may be persistent problem.

Other complications of lasik:

An important complication of lasik is difficulty in measuring the intraocular pressure of the operated eye (for diagnosis of glaucoma) and difficulty in calculating the intraocular lens power after cataract operation. Keep record of preoperative, operative and postoperative eye measurements for overcoming this complication. Other uncommon complications of Lasik are hole in macula, retinal detachment, neovascularization (appearance of blood vessels in cornea, which is normally devoid of any blood vessels), increase incidence of uveitis and blepharitis etc.
