Abstract

Background: The purpose of the study was to compare the visual acuity, contrast sensitivity, subjective visual satisfaction, and spectacle independence in patients implanted with apodized diffractive multifocal versus monofocal
intraocular lens following phacoemulsification. This was a 15-months prospective, interventional study.

Material and methods: In each of the 60 patients enrolled in the study, one eye was operated. In 30 patients, we implanted monofocal intraocular lens (IOLs) (Group I) and in 30 consecutive patients — multifocal IOLs (Group II). Follow-up visits at postoperative 1st, 4th, and 6th week were done. Distance and near visual acuity, contrast sensitivity at 3, 6, 12, and 18 cpd, refractive pseudophakic correction, and visual satisfaction by VF-14 questionnaire were assessed.

Results: Uncorrected and best-corrected distance visual acuity were comparable between the two groups (p > 0.05). 100% of patients in group I and 96.66% in Group II attained best-corrected vision of > 6/9. Uncorrected near visual acuity was significantly better in Group II (p < 0.0001). Sixteen out of 30 patients in Group II achieved unaided N6 vision. Corrected near vision was similar in the two groups. Mean near correction was much lower (+0.76 DS ± 0.86) in Group II. Photopic contrast sensitivity was better in Group I at lower frequencies (3 and 6 cpd). More satisfaction and spectacle independence was seen in Group II.

Conclusion: The apodised diffractive multifocal IOLs are a reasonable choice for patients who opt for freedom from glasses and understand its inherent limitation of reducing contrast to some degree.
