Modified monovision yields better intermediate, distance visual acuity
Modified pseudophakic monovision resulted in better binocular intermediate and distance visual acuity than conventional monovision, according to a study. However, conventional monovision provided better near visual acuity.
The prospective study included 82 patients who underwent bilateral implantation of a monofocal IOL. At 3 months postoperatively, investigators simulated modified monovision by adding a +0.75 D spherical lens to the nondominant eye or conventional monovision by adding a +1.75 D spherical lens to the nondominant eye.
A non-monovision control group comprised the same 82 patients in whom bilateral eyes were distance corrected without the addition of a spherical lens.
Mean binocular corrected intermediate visual acuity at 1 m was 20/19 and near visual acuity at 0.3 m was 20/51 with modified monovision.
Modified monovision yielded significantly better mean binocular intermediate visual acuity at 1 m than standard monovision (P = .0001).
However, modified monovision resulted in significantly worse near and intermediate visual acuity at 0.5 m (P < .0001).
In addition, modified monovision provided markedly better mean stereoacuity than conventional monovision (P = .0020).
