[Comparison of dysphotopsia effects in phakic and pseudophakic eyes using Rostock glare perimeter].

BACKGROUND

Pseudophakic dysphotopsia as unwanted side effect after cataract surgery are becoming increasingly important. The so-called glare perimetry allows a realistic quantification of these phenomena. The article presents the method on the example of healthy subjects and pseudophakic patients.

PATIENTS AND METHODS

Using glare perimetry phakic and pseudophakic subjects were examined for differences in disability glare. For this, data from 60 phakic persons of different ages (45 ± 17.1 years) were used. As pseudophakic subjects 31 carriers of monofocal lenses (70 ± 6.7 years) and 25 carriers of multifocal lenses (71 ± 8.5 years) were tested.

RESULTS

Disability glare was significantly smaller in the phakic group (1.00 ± 0.336°) than in the pseudophakic group (1.56 ± 0.622°). Among the pseudophakic eyes those with a multifocal lens (1.69 ± 0.367°) were significantly more sensitive to glare than those with a monofocal lens (1.43 ± 0.492°).

CONCLUSION

Glare perimetry allows an objective quantification of effects of dysphotopsia under realistic conditions. Pseudophakic eyes show a higher sensitivity to glare than eyes with the natural clear lens. Here, eyes with multifocal lenses prove to be particularly sensitive to glare.
