“…This change is similar to that described by Hayashi et al in their studies on long-term changes in corneal astigmatism in pseudophakic eyes, of approximately 0.18 D over 10 years. 14 Although this would not seem to be a clinically relevant change, it might explain the small drop in uncorrected visual acuity between the one month and one year visit in our study.…”

Purpose To report medium-term visual acuity and refractive outcomes of patients with pseudoexfoliation implanted with toric or multifocal intraocular lenses (IOLs). Methods We retrospectively reviewed patients with pseudoexfoliation who had undergone phacoemulsification between 2016 and 2020 with at least 24 months follow-up. Results Mean follow-up was 44.17 ± 14.95 months. Toric IOLs were implanted in 48 eyes: mean uncorrected LogMAR visual acuity one month after surgery was 0.03 ± 0.09, decreasing to 0.08 ± 0.11 at the last visit ( p = .01). Mean refractive cylinder was −0.12 ± 0.36 diopters one month after surgery and −0.25 ± 0.44 diopters at the last follow-up visit, p = .012. Multifocal IOLs were implanted in 42 patients: binocular uncorrected distance visual acuity was −0.02 ± 0.04 one month after surgery and 0.01 ± 0.05 at the last visit ( p = .004); near acuity was 0.01 ± 0.03 and 0.04 ± 0.06 respectively ( p = .001). In eyes with pseudoexfoliation, absolute spherical equivalent prediction error was 0.22 ± 0.20 diopters for toric and 0.21 ± 0.19 diopters for multifocal IOLs. One month after surgery 68.6% of eyes with toric IOLs and 74.2% of eyes with multifocal IOLs were within ±0.25 diopters of target spherical equivalent and 91.6% and 90.5% were within ±0.5 diopters, respectively. Spherical equivalent did not change significantly during follow-up for either group. Conclusion Prediction error in eyes with pseudoexfoliation implanted with toric or multifocal IOLs was low and similar to values reported for normal eyes. Postoperative refractive cylinder with toric IOLs was low, with little change during follow-up. Visual function in patients receiving multifocal IOLs was excellent. Therefore, the implantation of these IOLs in eyes with pseudoexfoliation does not seem to cause medium-term problems.

OBJECTIVE: To examine the incidence and characteristics of eyes with oblique astigmatism strati ed by meridian, age, sex, and eye side (left to right). METHODS: One thousand eyes of 1000 patients with oblique corneal astigmatism underwent videokeratographic examination, and was classi ed into 4 meridian categories: 1) 31°-45°, 2) 46°-59°, 3) 121°-135°, and 4) 136°-149°. Amounts of regular and irregular astigmatism, and the vertical/horizontal (Rx) and oblique astigmatism components (Ry) decomposed using vector analysis were compared among the 4 categories and age groups, and between sexes and eye sides. RESULTS: Incidences of the 4 meridian categories were similar, and did not differ signi cantly among age groups or between sexes. The incidence was signi cantly greater in eyes in meridian categories 1 and 2 in the left eye and categories 3 and 4 in the right eye, and signi cantly greater in men in their 40s and 50s and in women in their 70s and 80s (P < 0.001). The mean regular astigmatism, asymmetry and higherorder irregularity components, and Rx and absolute Ry signi cantly increased with age (P ≤ 0.037). The mean regular and irregular astigmatism, and absolute Rx and Ry did not differ signi cantly among the 4 categories, or between sexes or left and right eyes.CONCLUSIONS: The incidence of oblique astigmatism was signi cantly greater in the temporal side meridians, and the incidence in women increased with age. The degree of oblique astigmatism increased with age, with an increase in irregular astigmatism.

Long-term changes in manifest refraction subsequent to cataract surgery

Abstract: Spherical power did not change and refractive astigmatism changed toward against-the-rule (ATR) astigmatism over ≥7 years after cataract surgery in pseudophakic eyes, whereas hyperopic and ATR shifts occurred in phakic eyes.
