[Assessment of visual function and satisfaction in pseudophakic monovision].

PURPOSE: To investigate the visual function and acceptability of pseudophakic monovision in relation to age.

METHODS

We examined 82 cases (age: 49-87 years) with pseudophakic monovision. All cases were undergone monovision using monofocal intraocular lens (IOLs). The cases were classified into three groups based on their age (A, less than 60 years; B, between 60 to 70 years ; and C, more than 70 years). Refractive error, visual acuity at various distances, contrast sensitivity, and near stereopsis were measured. Using a questionnaire, patient satisfaction before and after cataract surgery was evaluated.

RESULT: The mean difference in spherical equivalent refractive error between both eyes was 2.27 D (A, 2.39D; B, 2.30D; and C, 2.20 D). Most cases had a binocular uncorrected visual acuity of 20/25 or better at all distances. For contrast sensitivity, binocular summation was observed at 1.5 to 6 cycles/ degree. Near stereopsis was in the normal range, which was less than or equal to 100 seconds of arc. Moreover, it was found that 82% of the patients were satisfied with the results (A, 68%; B, 86%; and C, 93%).

CONCLUSION

Pseudophakic monovision may be an effective approach for managing loss of accommodation after cataract surgery especially in patients over 60 years of age. However, careful selection of patients should be carried out.
