OBJECTIVES: To investigate the effectiveness of presbyopia correction using multifocal soft contact lenses (MF SCLs) for pseudophakic subjects with monofocal intraocular lenses (IOLs).
METHODS: In 11 subjects, after monofocal IOL implantation, disposable MF SCLs (Dailies Total 1 Multifocal, Alcon) were daily used for 3 months. Binocular visual acuity between 0.3 and 5 m was measured using an all-distance vision tester (AS-15, Kowa) at 1 and 3 months and compared before and during MF SCL wear. Binocular contrast sensitivity testing was conducted under mesopic and photopic illuminations at 1 month.
RESULTS: The mean manifest refraction spherical equivalent before MF SCL wear was -0.36 D. The add powers of used MF SCLs were +1.25, +2.00, and +2.50 D in 1, 16, and 5 eyes, respectively. The mean binocular visual acuities during MF SCL wear were 20/20 or better between 0.5 and 5 m and significantly improved at 0.7 m or less (P<0.025). There was no change in the mesopic contrast sensitivity, whereas the photopic contrast sensitivity at 18 cycles per degree was degraded during MF SCL wear.
CONCLUSIONS: The use of MF SCL was effective for presbyopia correction in pseudophakic subjects with monofocal IOL, and favorable binocular vision would be obtained in a range from distance to intermediate.
