LASIK Complications and Risks (3)


6. Regression
Patients with severe myopia, hyperopia and astigmatism are more likely to experience regression. Regression is gradual decrease in visual acuity over time after LASIK. If significant regression occurs, enhancement surgery may be needed to achieve permanent results.

7. Epithelial Ingrowth
Epithelial Ingrowth happens when the epithelium (corneal surface cells) grows beneath the corneal flap created during the LASIK surgery and causes blurry vision, irritation or swelling. This problem is treated easily by gently lifting the flap and removing the ephitelial cells.

8. Diffuse Lamellar Keratitis (DLK)
DLK is also popular with the name of Sands of Sahara. It is a general inflammation caused by the appearance of dead cells underneath the LASIK flap. It can be prevented by maintaining a clean interface between corneal flap and the underlying corneal stroma. If DLK does occur, steroid eye drops are used to suppress inflammation. However in severe DLK cases, an eye surgery is needed to lift the corneal flap and remove the inflammatory cells. DLK potentially leads to permanent vision loss if not treated promptly.

9. Central Lamellar Keratitis (CLK)
CLK is a different form of lamellar keratitis that appears within the first 24 to 48 hours. Its treatment is similar to DLK, but additional enhancements are needed after recovery.

10. Loss of Best Corrected Vision
Only a small number of patients may experience a slight loss of visual sharpness following LASIK. It means that even with glasses, you are no longer to be able to read the 20/20 line on the eye chart, but can still read the 20/30 or 20/40 line without glasses or contact lenses. Losing more than two lines of vision is a very rare condition - less than 1% in statistical result.
