“…Patients with good initial VA (0.10 logMAR, 20/25 or better) but with symptoms of decreased vision quality (glare and halos) also showed a statistically significant improvement in OSIs after capsulotomy. A similar study on eyes with good initial VA (20/20) showed significant improvements in intraocular stray light using the compensation comparison method (8) . We have strengthened this evidence with our DPRI findings showing OSIs and thus removing subjectivity from the data acquisition process.…”

“…Forward light scatter has also been proposed as a mechanism to evaluate visual function in patients with visually significant PCO (7) . Forward light scatter detects the light that does not come into focus on the retina because of aberrations within the optical system, resulting in halos, glares, and difficulty during driving under scotopic conditions (8) . Double-pass retinal imaging (DPRI) can be used to analyze the point-spread function (PSF) directly from the retinal image; it is a validated and reproducible technology designed to evaluate forward light scatter through the optical system (9)(10)(11) .…”

The purpose of this study was to objectively assess the optical vision quality of patients before and after Nd:YAG capsulotomy for posterior capsular opacification using a double-pass retinal imaging system. Methods: We retrospectively analyzed the data from 26 pseudophakic eyes with posterior capsular opacification that underwent Nd:YAG capsulotomy. The objective scatter indices, modulation transfer function cutoff frequencies, Strehl ratios, and logMAR corrected distance visual acuities were assessed before and after YAG capsulotomy with a double-pass retinal imaging system (OQAS II, Visiometrics, Spain). We also analyzed data from a subgroup of 10 patients with pre-YAG corrected distance visual acuity of 0.10 logMAR (20/25) or better. Results: Vision quality indices improved in all 26 eyes, resulting in a statistically significant improvement in the corrected distance visual acuity (p=0.007), objective scatter index (p=0.001), modulation transfer function cutoff frequency (p=0.001), and Strehl ratio (p=0.020). The overall mean improvements included 0.12 ± 0.04 logMAR for corrected distance visual acuity, 2.84 ± 0.76 for objective scatter index, 12.29 ± 2.77 for modulation transfer function cutoff frequency, and 0.06 ± 0.03 for Strehl ratio. Our sub-analysis of 10 eyes with 0.10 logMAR (20/25) corrected distance visual acuity or better also showed a statistically significant improvement in the mean objective scatter index (0.76 ± 16; p=0.001), resulting in approximately 35% decrease in intraocular light scatter. Conclusions: The objective vision quality measurements as assessed by the double-pass retinal imaging system showed a significant improvement after YAG capsulotomy. This suggests that the objective scatter index improves after YAG capsulotomy, even in eyes with pre-YAG 0.10 logMAR (Snellen 20/25) corrected distance visual acuity or better.

Purpose. To investigate the effects of capsulotomy shape on the visual acuity and visual quality after neodymium: yttrium aluminum garnet laser capsulotomy. Methods. In this study, a total of 42 eyes from 35 patients with posterior capsule opacification were divided into the circular and cruciate groups. The corrected distance visual acuity (CDVA), objective scatter index (OSI), modulation transfer function cutoff (MTF cutoff), Strehl ratio, and Optical Quality Analysis System values at contrasts of 100%, 20%, and 9% (OV-100, OV-20, and OV-9) were measured at precapsulotomy and 1 week and 1 month postcapsulotomy. The pseudophakic dysphotopsia questionnaire (PDQ) was used to evaluate the subjects’ satisfaction with treatment. Results. OSI values were significantly higher in the cruciate group than in the circular group at 1 week and 1 month after capsulotomy (P=0.013 and P<0.001). No significant difference was found in the OSI values between the two groups before capsulotomy (t = 0.52; P=0.61). The decrease in OSI was higher in the circular group than in the cruciate group at 1 week and 1 month after capsulotomy (P=0.036 and P=0.019). No significant differences were found in the Strehl ratio, MTF cutoff, CDVA, OV-100, OV-20, and OV-9 between the two groups at 1 week and 1 month after capsulotomy (P>0.05). The PDQ results showed that patients with circular-shaped capsulotomy complained less with intolerance of bright lights than those with cruciate-shaped capsulotomy. Conclusions. Circular-shaped capsulotomy can induce less intraocular light scattering and increase patient satisfaction.
