Abstract Details

Purpose:

To evaluate visual acuity at distance, intermediate and near with and without multifocal soft contact lens (SCL) on eyes after binocular implantations of monofocal intraocular lenses (IOLs).

Setting:

Miyata Eye Hospital, Miyakonojo, Miyazaki, Japan

Methods:

This prospective study enrolled 10 bilateral pseudophakic patients (age: 46-61 years) with monofocal IOLs, and used daily disposable multifocal contact lenses (Dailes Total-1 Multifocal, Alcon) that provided near through distance vision corrections from in the center to peripheral areas. The additional power was selected by the patient's preference. Uncorrected and SCL-corrected distance and near (30 cm) visual acuities were measured before and 1 month of SCL use, respectively. The binocular visual acuities from 0.3 m to 5.0 m were measured using AS-15 (Kowa). Photopic and mesopic binocular contrast sensitivities were also examined using Optec6500 (Stereo Optical).

Results:

Mean manifest refraction spherical equivalent and astigmatism were ‐0.45 D and +0.70 D, respectively. There was no difference in distance visual acuity. Near visual acuity was significantly better using multifocal SCLs than before use (P=0.002). In the binocular visual acuities from 0.3 m to 5.0 m, 20/20 or better were obtained between 5.0 and 1.0 m both with and without the uses of SCL, while the use of SCL provided better visual acuities between 0.7 and 0.3 m (P<0.04) and retained 20/20 or better until 0.5 m. No significant difference was measured for photopic or mesopic contrast sensitivity (P>0.08).

Conclusions:

The use of multifocal SCL provides effective presbyopia correction for pseudophakic subjects with monofocal IOLs.
