Monovision Cataract Surgery & Near Vision

Monovision Cataract Surgery is a technique that is used to help patients increase their range of clear vision after a cataract operation. The technique of monovision has been used for many years by contact lens wearers as well as patients with presbyopia having laser eye surgery for the Laser Vision Correction of nearsightedness, farsightedness and astigmatism. 

The monovision technique is simply adjusting the optical correction in each eye so that the dominant eye is corrected for clear distance vision and the non-dominant eye is corrected for improving near or intermediate range vision. For patients who have been wearing monovision contact lenses successfully, or who have had monovision LASIK and are pleased with the vision, taking the step into monovision cataract surgery is a natural progression. For others, they must consider the possible benefits as compared to those provided by near vision presbyopia correcting multifocal lens implants as some 30% of monovision patients fail to adapt adequately to the “blended” vision. 

Researchers reporting in the May 2011 Journal of Refractive Surgery studied the optimal monovision prescription that should be used in order to get the highest levels of patient acceptance and overall visual acuity and depth perception. They concluded that the prescription range of 1.00 D-2.00 D of monovision correction was the maximum range and that the optimal prescription for monovision cataract surgery was 1.5 D. While this is useful information, patients should understand that a 1.5 D near correction may very well be insufficient for them to perform their daily tasks comfortably without needing readers or bifocals. 

The only reliable way for you or someone you know with a cataract to find out if you are candidates for monovision cataract surgery or near vision presbyopia correcting lens implants after cataract surgery is to schedule a cataract and lens implant evaluation at D’Ambrosio Eye Care by calling 800-325-3937.
