Abstract Details

Purpose:

To determine the visual function of pseudophakic individuals using an objective measure, the objective scatter index, 4 years post-operatively.

Setting:

Niagara Health System, Canada

Methods:

Retrospective analysis of pseudophakic eyes following cataract surgery, with at least 4 years of follow-up. The OSI was obtained using the optical quality analysis system (OQAS; Visiometrics). The artificial exit pupil diameter in the system was set at 4.0 mm. Patients with healthy eyes, visual acuity greater than decimal 0.67 and refractive errors less than 1.0 D were assessed.

Results:

Data on 250 eyes was analyzed. Approximately 25% of the eyes were excluded due to tear film abnormalities. Remaining study eyes were divided into the type of hydrophobic acrylic IOL implanted. The two groups were matched for age, power of IOL implanted, presence of DM, and presence of capsulotomy. One group had significantly decreased visual acuity (0.80 +/- 0.15 vs 0.86 +/- 0.12), increased OSI (1.55 +/- 0.67 vs 1.35 +/- 0.62) and lower duration of follow-up (66 +/- 14.77 vs 71 +/- 14.09 months).

Conclusions:

Long term follow-up of intraocular lenses reveals that OSI and visual acuity differ. Possible causes will be considered.
