Optic Capture in a patient with Congenital Lens Coloboma

PURPOSE: To report the effect of the optic capture in the treatment of congenital lens coloboma. METHODS: A 5-year old boy was transferred to Maryknoll Hospital with congenital lens coloboma in his right eye. Lens coloboma at superotemporal area and capsular cataract around the coloboma was observed in the slit lamp examination. Posterior continuous curvillinear capsulorrhexis was performed after irrigation and aspiration of the lens. Optic was captured behind the posterior capsule while its haptics were placed in the sulcus. RESULTS: Best corrected visual acuity improved from preoperative 20/63 to 20/20 postoperatively. Intraocular lens decentration and rotation and other sight threatening complications were not found during the follow up period. CONCLUSIONS: Optic capture is thought to be a safe and effective means to prevent IOL decentration and posterior capsular opacity in the treatment of congenital lens colobomas.

Comparision of the Three Different Hydrophilic Acrylic Intraocular Lenses

PURPOSE: To evaluate the stability of three different hydrophilic acrylic intraocular lenses (IOLs), which have different shapes. IOLs included in this study are three-piece acrylic IOL with PMMA (Polymethylmethacrylate) haptics (Hydroview(R) H60M, Bausch &Lomb, U.S.A), one-piece acrylic IOL with broad optic-haptic junction (Centerflex(R) 570H, RAYNER, UK), and one-piece acrylic IOL with narrow optic-haptic junction (Aquasens, Ophthalmic Innovations International, U.S.A). METHODS: We evaluated 69 patients (100 eyes) who had undergone cataract surgeries and who had hydrophilic acrylic IOLs implanted from September, 2003 to March, 2004. Forty eyes implanted with three-piece acrylic IOL with PMMA haptics, 40 eyes implanted with one-piece acrylic IOL with broad optic-haptic junction, and 20 eyes implanted with one-piece acrylic IOL with narrow optic-haptic junction were included. Slit lamp examination, best corrected visual acuity (BCVA), anterior chamber depth (ACD), refraction, and IOL decentration were evaluated at one week and at one, three, and six months postoperatively. RESULTS: There was no statistically significant difference in BCVA, ACD, mean SE or decentration between patients implanted with three different types of hydrophilic acrylic IOL during the 6 month follow-up period (P>0.05). However, Postoperative myopic shift was discovered in 4 eyes (4/20) with Aquasens. CONCLUSIONS: There were no statistically significant difference in the Stabilities of the 3-different hydrophilic acrylic IOLs. However, patients who were implanted Aquasens shold be observed carefully because Aquasense has the posibilitiy to have myopic shift more than 1 Dioptor.
