RE: Brent A. Hanson
Date of Exam: 10-20-99

To Whom It May Concern:

On October 20, 1999 I last saw Brent Hanson who has undergone multiple refractive excimer laser procedures to each eye. His vision was 20/25 OD without correction and 20/40 OS without correction. Examination of his corneas revealed very significant haze superficially in the right eye from previous photorefractive keratectomy by excimer laser. Underneath that he has evidence of a LASIK procedure with a cap in good position. The left eye has moderate central corneal haze. Corneal topography by orb scan reveals moderate superior decentration of the central ablation zone. Topography of the left eye reveals a remarkably thinned cornea only 192 microns thick at the thinnest point. There is also evidence of ectasia of the posterior cornea.

This patient is very unhappy about the poor quality of his vision. In the right eye, it is due to the superficial haziness from previous excimer laser treatments in the decentered ablation zone. Poor vision in the left eye appears to be due to mild to moderate distortion caused by posterior corneal ectasia which is secondary to the very thin cornea.

Sincerely,

Bradford B. Pazandak M.D.
