Abstract Details
Purpose:
To evaluate the visual outcomes, functional vision and patient satisfaction with new ERV Intraocular Lenses in patients undergoing bilateral implantation with micro-monovision.
Setting:
Nethradhama Super Speciality Eye Hospital, Bangalore
Methods:
This prospective, consecutive, interventional study included cataract patients undergoing bilateral implantation of ERV lens with micro-monovision. The dominant eye was corrected for emmetropia, while the non-dominant eye was targeted for a residual myopia of -0.75D. The main outcome measures studied were postoperative uncorrected distant visual acuity (UDVA), defocus curve, contrast sensitivity. The Salzburg Reading Desk (SRD) was used to assess uncorrected and distant corrected near visual acuity (UNVA, DCNVA) at 40 cm and intermediate visual acuity (UIVA, DCIVA) at 60 and 80cm respectively. Mean follow up was 50±11 days.
Results:
38 eyes of 19 patients with mean age of 62.6 years were included. At one month , the mean UDVA was 0.01±0.1 , which improved from pre CDVA value of 0.54±0.35 logMAR. UDVA was 6/6 in 78.9% eyes, 6/5 in 10.5% eyes and 6/7.5 in 10.5% eyes. The binocular UDVA was 6/6 in all patients. The mean VA with SRD at 40, 60 and 80 cm were 0.154±0.02, 0.074±0.01 and 0.056±0.02 logMAR units with reading speeds of 98.12±21, 115.1±14 and 109.1±25 words/min respectively. Mean VA in the defocus range of +1.5 to -1.5D was between 6/9-6/6. 75% patients reported seeing a single halo around light at night, which did not seem to bother them.
Conclusions:
The new Extended Range of Vision IOLs were successful in providing excellent uncorrected visual acuity at distant, near and intermediate distances with good reading speeds. Patient satisfaction was very high with 100 % spectacle independence and minimal complaints of dysphotopsia.
