Conventional pseudophakic monovision – visual function, patient satisfaction and complications

Introduction
To evaluate visual function, patient satisfaction and complications after cataract surgery with conventional pseudophakic monovision in a 3-month follow-up.

Material and methods
The following parameters were evaluated in a group of 20 selected patients (40 eyes) mean age: 62.15 ± 7.22 years, who underwent bilateral cataract surgery with monofocal lens implantation (Alcon SA60AT) in the conventional monovision procedure 3 months earlier (target refraction: dominant eye-emmetropia, fellow eye – -2.0 D): binocular uncorrected visual acuity for near, intermediate distance and distance (logMAR), contrast sensitivity (CS-CSV-1000), spectacle independence, patient satisfaction (Type Q) and complication rate.

Results
The mean prescription for distance was in -0.01 ± 0.14 D in dominant eyes, and -1.85 ± 0.19 D for near in nondominant eyes. Three months after surgery, patients had a very good binocular distance, near as well as intermediate visual acuities (-0.03 ± 0.09, -0.1 ± 0.11, and -0.39 ± 0.17, respectively). Binocular contrast sensitivity values under mesopic and photopic conditions for distance and under photopic conditions for near fell in the reference range for age. Most patients (80%) did not require any additional correction. Spectacle independence for distance, near and intermediate distances was 100%, 80% and 90%, respectively. General patient satisfaction was very high (9.40/10). There were no postoperative complications.

Conclusions
Cataract surgery with monofocal lens implantation during a conventional monovision procedure (E,-2.0 D) in a selected group of patients offered a very good binocular visual function, a substantial spectacle independence and overall patient satisfaction.
