Monovision is the one refractive procedure you can test-drive before committing to it. We fit you with contact lenses set to your planned monovision prescription and ask you to live in them for one to two weeks — driving at night, working at your screen, reading in dim light, doing whatever your ordinary week actually contains. Nothing predicts how well you will adapt more reliably than that.
Alongside the trial, we determine which eye leads. Eye dominance works much like handedness, and simple testing settles it: the dominant eye is usually corrected for distance and the non-dominant eye for near. Your job and your hobbies can change that plan, and so can what the trial tells us. If the trial is uncomfortable, we can soften the difference, switch eyes, or set the near eye for intermediate distance instead.
The treatment itself runs on iDesign 2.0 — a single three-second scan measuring wavefront and corneal topography together, 25 times more precise than a subjective refraction. It is the only LASIK platform FDA-indicated for monovision in nearsighted presbyopic patients, and Dr. Boutros was among the first surgeons in the world to offer it. Each eye then receives its own treatment pattern from the VISX STAR S4 IR excimer laser, planned against a nomogram refined across more than 40,000 procedures.
