Refractive Surgery Dilemma
نویسندگان
چکیده
A 33-year-old man seeking refractive surgery presented with refractive error of -1.75 -4.0×20° in the right and -0.75 -2.5×170° in his left eye in January 2009; best spectacle-corrected visual acuity (BSCVA) was 20/25+ and 20/20respectively. All ocular examinations were unremarkable and family history for keratoconus was negative. He had previously obtained consultation for refractive surgery in 2000; at that time, intervention had been withheld due to unspecified concerns. Previous refractive data was not available except for an Orbscan printout. Due to presence of asymmetric astigmatism, abnormalities on repeat Orbscan examination, and patient’s interest in wavefrontguided (WFG) ablation, aberrometry (Zywave II, Bausch and Lomb, Rochester, USA) was obtained. Orbscan and Zywave printouts are shown in figures 1 through 3. Herein, we present the views of three experienced refracttive surgeons in the approach to excimer surgery in this particular case.

Background and Objective: Ocular biometry refers to the measurement of the axial length of the eye and thickness of the intraocular structures. This process is routinely performed for all patients before cataract surgery. The accuracy of the biometric data is directly associated with the refractive status after cataract surgery. Currently, two methods of biometry, namely ultrasound and optical ...
