A Comparison of LASIK Outcomes Using Two Femtosecond Lasers

January 10, 2020

Overview

Edward E. Manche of Stanford University is holding a study on the differences in the results of LASIK eye surgery performed with two femtosecond lasers. Patients will undergo an eye exam with computerized videokeratography to see if they are suitable for the study. Those who undergo surgery will be treated with either the Intralase IFS 150 or VisuMax. 

 

Study Information

This study has an estimated enrollment of 50 participants. The laser that will be performed on patients’ eyes will be randomly assigned on the day of surgery. They will be given antibiotic eye drops for one week after surgery and vigamox ophthalmic drops for four days after surgery. Flap thickness will be measured one month after surgery. The Cochet Corneal sensation, visual acuity, aberrometry, and questionnaires will be researched one month, three months, six months, and twelve months after surgery.

 

Inclusion Criteria

All sexes, ages 21 to 60 years old, are allowed to participate. To be included in the study, participants must have healthy eyes and nearsightedness between -0.25 diopters and -11.00 diopters with or without astigmatism of up to 5.00 diopters.

 

Exclusion Criteria

Those who are not allowed to participate include those who do not meet the age requirements and subjects who have corneal ectatic disorders.

 

Location

Those interested may participate in this study at Byers Eye Institute at Stanford in Palo Alto, California, 94303. Feel free to contact Linda Schwartz at 650 724-2864 or at lschwartz@stanfordhealthcare.org with any questions or concerns.
