Recent research has refined the art of monovision, providing insights into this widely used treatment for presbyopia, according to Edward E. Manche, MD.
Refractive surgeons are likely to enjoy good success if they aim for a maximum of 1.50 D of residual myopia in the non-dominant eye, exclude some patients with pre-existing strabismus, and monitor for signs that strabismus is emerging, Dr. Manche said.
“It’s still the most commonly employed option for presbyopia,” said Dr. Manche, professor of ophthalmology, Stanford University, Stanford, CA.
Monovision has been used for decades with contact lenses, with reported success rates ranging from 70% to 76%. In refractive surgery—including LASIK, PRK, conductive keratoplasty (CK) clear lens extraction, phakic IOLs, cataract surgery, and corneal inlays—the success rate ranges from 72% to 93%, he noted.
