ABSTRACT
Many refractive surgery patients are in the presbyopic or prepresbyopic age group and often experience difficulties with near vision after their myopia is corrected. Preoperatively, many of these patients are able to read by taking off their glasses; postoperatively, they may find they are no longer able to do so. Most patients choose to undergo refractive surgery in order to decrease their dependence on spectacles and are therefore not happy with the prospect of needing reading glasses (1-3). One means of addressing the problem of presbyopia is monovision refractive surgery, in which one eye is surgically corrected for distance vision and the other eye for near vision (1-7). The near vision eye may be placed in focus at a reading distance (33 cm) or at an intermediate distance (for example, at 50 cm for computer use). The monovision approach has been successfully applied to laser-assisted in situ Keretomileusis (LASIK) and to presbyopic contact lens wearers.
