PURPOSE.To quantify the changes in retinal straylight that occur after laser-assisted subepithelial keratectomy (LASEK). METHODS. This prospective study included 86 eyes of 49 patients who were scheduled for LASEK surgery. Patients were divided into groups based on their preoperative contact lens wear habits: rigid lenses (RCL), soft lenses (SCL), spectacles after a period of contact lenses (SaC), and spectacles only (Specs). Retinal straylight was tested before surgery and 6 months after surgery with the compensation comparison method. Straylight was also compared to a normal reference database. The difference with the average straylight increase with age, called base-and age-corrected (BAC) straylight, was also studied. RESULTS. Before surgery, BAC straylight was found to be strongly elevated, with a value of 0.15 Ϯ 0.14 log units. After LASEK, this decreased to 0.00 Ϯ 0.14 log units. The reduction was significant (paired t-test, P Ͻ Ͻ 0.01) and correlated with preoperative BAC straylight levels (r 2 ϭ 0.332; P Ͻ Ͻ 0.01). There was no correlation between the straylight change and the spherical equivalent of the laser refractive correction (r 2 ϭ 0.042; P ϭ 0.059). Preoperative wear of soft contact lenses increased the BAC straylight by approximately 0.06 log units, with respect to the spectacles groups (P Ͻ 0.05, unpaired t-test), but after surgery, this difference was no longer found (P Ͼ 0.05). CONCLUSIONS. Higher than normal preoperative BAC straylight was found to normalize after LASEK refractive surgery. Wearing soft contact lenses causes an additional increase in preoperative BAC straylight that is eliminated after LASEK. (Invest Ophthalmol Vis Sci.

This case report describes the one-year results of the implantation of a sectorial and foldable artificial iris in a phakic eye. To our knowledge, this is the first such report with a follow-up of 1 year. No perioperative or postoperative complications were seen. Corrected distance visual acuity remained unchanged (left eye, 1.5/10), the subjective complaints of glare and photophobia improved considerably, and the patient was very satisfied with the aesthetic result.
