This study was performed to compare the incidence of posterior capsular opacity (PCO) and refractive errors between hydrophilic (ACR6D, Corneal (R) ) and hydrophobic (MA60BM, AcrySof (R) ) acrylic intraocular lenses (IOLs) over a 3-year follow-up after phacoemulsification surgery. The patients with AcrySof (R) implanted in one eye and Corneal (R) in the other eye were categorized as Group 1 (n=28), while those with one or both eyes implanted with IOLs of the same kind were categorized as Group 2 (AcrySof (R), n=90; Corneal (R), n=95). Refractive errors were evaluated at 3 months and 3 years postoperatively. The incidence of visually significant PCO was investigated 3 years postoperatively. Postoperative refractive values at 3 months were not significantly different between the two groups. However, refractive values at 3 years were significantly different between two IOLs in both groups [AcrySof (R) -0.37 +/- 0.43D, Corneal (R) -0.62 +/- 0.58D in Group 1 (p=0.04) ; AcrySof (R) -0.38 +/- 0.52, Corneal (R) -0.68 +/- 0.54 in Group 2 (p< 0.01) ]. The incidence of visually significant PCO was 14% and 32% in Group 1, and 13% and 28% in Group 2, for the AcrySof (R) and Corneal (R) implants, respectively. The incidence of visually significant PCO of hydrophilic acrylic IOLs was higher than that of hydrophobic acrylic IOLs in the 3-year follow-up. The postoperative 3-year refractive value of Corneal (R) showed myopic shift.

Purpose: We analyzed the effects of low-dose atropine on myopic progression in elementary schoolchildren aged 6-11 years. Methods: Medical records were retrospectively reviewed before and after 6 months of low-dose atropine eyedrops. Myopia was defined as a spherical equivalent < -1 diopter. Low-dose atropine eyedrops (atropine sulfate 0.125% [w/v]) and artificial tear eyedrops (sodium hyaluronate 0.1% [w/v]) immediately afterwards were applied to both eyes daily, and all children regularly visited us for measurement of refractive power, axial length, pupil diameter, and near-point accommodation. symptoms (headache, light sensitivity, near-work disturbance, allergic reaction, dry eye, and poor night vision) were recorded. Results: A total of 116 patients were included. Atropine was prescribed for 65 patients, the remaining 51 patients constituted the control group. In the atropine group, the mean age was 10.2 ± 1.8 years and 23 patients (35.4%) were male. At the initial visit, the mean refractive power was -4.7 ± 2.1 diopters (D) (-1.0 to -10.5) and the mean axial length was 24.95 ± 1.02 mm (22.58-27.99). At the 6-month follow-up, the change of refractive power was -0.9 ± 1.1 D (-0.75 to -4.75) and the change of axial length was 0.47 ± 0.39 mm (0.01-1.6). However, 6 months after application of low-dose atropine eyedrops, the change of refractive power was -0.1 ± 0.2 D (0 to -0.25) and the change of mean axial length was 0.15 ± 0.23 mm (0-1.05). The mean pupil diameter was 6.7 ± 0.6 mm (5.3-9.3) and the near accommodation point was 6.1 ± 2.0 cm (3.1-11.0). Two patients (3.1%) complained of near-work disturbance but none stopped taking the eyedrops. Conclusions Significant decreases in the changes of refractive power and axial length were evident in myopic elementary schoolchildren after low-dose atropine therapy. Low-dose atropine attenuates myopic progression without severe complications.
