Flap Complications

Possible complications resulting from Lasik surgery include (potential complications are not limited to those included in this list):

The following sporadically reported visual symptoms may occur following LASIK flap creation with the IntraLase® FS or iFS® Laser.

Transient Light Sensitivity Syndrome (TLSS)

Transient Light Sensitivity Syndrome is characterized by symptoms of mild to severe light sensitivity which manifests between two and six weeks postoperatively. Patients experience no decrease in uncorrected or best spectacle-corrected visual acuity. The incidence of this sensitivity is observed in approximately 1% of patients who undergo flap creation with the IntraLase® FS laser. Patients respond to the use of hourly topical steroids such as Pred Forte, and most report improvement within one week of treatment.

Peripheral Light Spectrum (PLS)

Peripheral Light Spectrum (PLS) is a temporary phenomenon whereby patients report the perception of a spoke-like spectrum of light in the periphery of their vision. PLS has no clinical examination findings and no effect on visual acuity; however the potential diffractive effects may be bothersome to some patients. Reported in only 0.03% of cases, the onset of symptoms occurs during the immediate postoperative period, and typically resolves within three months but may be slightly persistent in rare cases. The visual impact of PLS is clinically inconsequential for the vast majority of patients.
