Which is better: Multifocal or Monofocal IOL?
Journal Title: People's Journal of Scientific Research. - Year 2016, Vol 9, Issue 1
Abstract
A comparative study was conducted for assessing multifocal IOLs and standard monofocal lenses on visual acuity, subjective visual satisfaction, spectacle dependence, glare and contrast sensitivity among two groups of 20 patients each undergoing cataract surgery in a tertiary care hospital. First and Second Group were implanted with refractive-diffractive multifocal IOL and monofocal IOL of the same material respectively. Lenticular opacity grading, corneal astigmatism, axial length, and refractive status of each patient were assessed pre-operatively. Uncorrected visual acuity, best corrected visual acuity, distance vision, near vision, spectacle dependency and subjective satisfaction of each patient were noted post operatively on completion of Day 1, Week 1, Month 1 and Month 3. The uncorrected near visual acuity was significantly better in multifocal group, whereas the corrected distance visual acuity was better in the monofocal group. Patients with monofocal IOL reported fewer problems with nighttime driving and halos. The multifocal IOLs provided better near vision and significantly reduced spectacle dependency as compared to monofocal IOLs.
