Comparison of Clinical Outcomes between Different IOL Sizes after Microincisional Cataract Surgery

PURPOSE: To compare clinical outcomes between different IOL sizes after microincisional cataract surgery. METHODS: Retrospective chart review was done in 68 eyes of 68 patients who underwent phacoemulsification and implantation with two different-sized aspheric IOLs (AKREOS MI60 Bausch & Lomb, Inc., Rochester, NY). The patients were divided into 2 groups: group I consisted of 38 eyes between 15.5-22.0 diopter (D) (optic size 6.0 mm, overall size 10.7 mm), and group II consisted of 30 eyes between 22.5-30.0 D (optic size 5.6 mm, overall size 10.5 mm). The best corrected visual acuity (BCVA), refractive error, and anterior chamber depth (ACD) were measured preoperatively and postoperatively and were compared between groups. RESULTS: Postoperative 6 month BCVA was 0.08 +/- 0.10 D in group I and 0.07 +/- 0.11 D in group II. During the same period, the spherical equivalent was -0.32 +/- 0.65 D in group I and -0.16 +/- 0.59 D in group II (p > 0.05). There were no significant differences in ACD or refractive error during the postoperative period (p > 0.05). CONCLUSIONS: Comparison of postoperative visual acuity and spherical equivalent between different sizes of Akreos MI-60(TM) IOLs showed no differences.

Comparison of Visual Function Between Two Aspheric Intraocular Lenses After Microcoaxial Cataract Surgery

PURPOSE: To compare the visual function and postoperative refraction between two aspheric intraocular lenses (IOLs) after microcoaxial cataract surgery. METHODS: A prospective analysis of 60 eyes of 58 patients who had undergone microcoaxial phacoemulsification and implantation of aspheric IOLs (AcrySof IQ, 30 eyes; Akreos MI60, 30 eyes) was performed. The best corrected visual acuity (BCVA), spherical equivalent, intraocular pressure (IOP), corneal thickness, endothelial cell density (ECD), predictability of postoperative spherical equivalent, higher order aberrations, contrast sensitivity test, satisfaction, and glare were evaluated during the follow-up period of three months. RESULTS: There were no significant differences in BCVA, spherical equivalent, IOP, corneal thickness, or ECD (p>0.05). The predictability of the postoperative spherical equivalent in the AcrySof IQ and Akreos MI60 IOL groups was not significantly different (p=0.59), and the two groups showed good anterior-posterior stability during the postoperative three months. There were no significant differences in higher order aberrations, contrast sensitivity test, satisfaction or glare (p>0.05). CONCLUSIONS: Both AcrySof IQ and Akreos MI60 implantation groups showed similar visual functions and postoperative spherical equivalents after microcoaxial cataract surgery.

Comparison of Clinical Results Between Two Spherical Aberraion-Free Intraocular Lenses

PURPOSE: To compare the postoperative outcomes between Akreos MI60 and Akreos AO intraocular lens (IOLs) after cataract surgery. METHODS: A prospective analysis among 55 eyes of 55 patients who had undergone microcoaxial phacoemulsification and implantation of aspheric IOLs (Akreos MI60, 30 eyes; Akreos Adapt-AO, 25 eyes) was performed. The best corrected visual acuity (BCVA), spherical equivalent, intraocular pressure (IOP), corneal thickness, endothelial cell density (ECD), surgically induced astigmatism (SIA), predictability of postoperative spherical equivalent, higher order aberrations, and contrast sensitivity test were evaluated during the follow-up period of 3 months. RESULTS: There were no significant differences in BCVA, spherical equivalent, IOP, corneal thickness, ECD, SIA, higher order aberrations and contrast sensitivity test (p>0.05). The predictability of postoperative spherical equivalent in the Akreos Adapt-AO (-0.57+/-0.22D) represented statistically significant myopic shift compared with the Akreos MI60 group (-0.05+/-0.69D) (p=0.02). CONCLUSIONS: Both the Akreos MI60 and the Akreos Adapt-AO implantation groups performed similiarly, following cataract surgery, showed similar visual function.
