Monovision and LASIK.

BACKGROUND: Many LASIK patients are early and mid-presbyopes. Monovision is commonly targeted for these patients because of demographics. Considerations are reduced stereopsis, reduced acuity, night driving, and liability. CASE REPORTS: Case studies are used to illustrate contact lens and alternative trials for presbyopic and prepresbopic monovision LASIK patients. CONCLUSION: A preoperative monovision contact lens trial can be used to demonstrate monovision effects to the candidate for refractive surgery. Selection of add power, selection of distance and near eye, residual astigmatism, management, and gradual transistioning with regards to adaptation are discussed.
