Abstract
Purpose: To evaluate two intraocular lens (IOL) models with a circular haptic configuration designed to better distribute forces within the capsular bag over 360 degrees.Setting: University and Maria Middelares hospitals, Antwerp, Belgium.Methods: Two IOLs with circular haptics were evaluated for 6 months after implantation: a one-piece, all-poly(methyl methacrylate) (PMMA), Corneal IS M 5.5 lens with a 5.5 mm biconvex optic, overall diameter of 9.8 mm, and two semicircular open haptics (n = 103); a plano-convex, all-PMMA, modified Anis lens with a 5.5 mm plano-convex optic, total diameter of 10.0 or 11.0 mm (depending on diopter), and closed-loop haptics (n = 335). All lenses were inserted through a 5.5 mm scleral incision after phacoemulsification and placed in the capsular bag through a 4.5 mm curvilinear capsulorhexis. The IOLs centered without being rotated.Results: Six months after implantation, the IOL optics were well centered, even in eyes with an eccentric capsulorhexis (19%). In two eyes with partial zonulysis and in seven with posterior capsule rupture, decentration of less than 0.5 mm was observed. Both lenses provided uniform capsular support without causing stress lines in the posterior capsule. There were no cases of capsule contraction syndrome. Posterior capsule fibrosis reducing visual acuity occurred in 4% of eyes in both series.Conclusion: The Corneal IS M 5.5 and the Anis lens with circular haptics prevented late optic decentration and, therefore, would be useful in cases of eccentric capsulorhexis, partial zonulysis, anterior radial tears, and posterior capsule rupture. These IOLs may also prevent capsular contraction.

(IOL) models with a circular haptic configuration designed to better distribute forces within the capsular bag over 360 degrees.Setting: University and Maria Middelares hospitals, Antwerp, Belgium.Methods: Two IOLs with circular haptics were evaluated for 6 months after implantation: a one-piece, all-poly(methyl methacrylate) (PMMA), Corneal IS M 5.5 lens with a 5.5 mm biconvex optic, overall diameter of 9.8 mm, and two semicircular open haptics (n = 103); a plano-convex, all-PMMA, modified Anis lens with a 5.5 mm plano-convex optic, total diameter of 10.0 or 11.0 mm (depending on diopter), and closed-loop haptics (n = 335). All lenses were inserted through a 5.5 mm scleral incision after phacoemulsification and placed in the capsular bag through a 4.5 mm curvilinear capsulorhexis. The IOLs centered without being rotated.Results: Six months after implantation, the IOL optics were well centered, even in eyes with an eccentric capsulorhexis (19%). In two eyes with partial zonulysis and in seven with posterior capsule rupture, decentration of less than 0.5 mm was observed. Both lenses provided uniform capsular support without causing stress lines in the posterior capsule. There were no cases of capsule contraction syndrome. Posterior capsule fibrosis reducing visual acuity occurred in 4% of eyes in both series.Conclusion: The Corneal IS M 5.5 and the Anis lens with circular haptics prevented late optic decentration and, therefore, would be useful in cases of eccentric capsulorhexis, partial zonulysis, anterior radial tears, and posterior capsule rupture. These IOLs may also prevent capsular contraction.</abstract><note>Presented in part at the Société Belges de lrerres de Contactes meeting, at Ophthalmologica Belgica, Brussels, Belgium, November 1994.</note><note>None of the authors has a proprietary or financial interest in either lens described.</note><relatedItem type="host"><titleInfo><title>Journal of Cataract & Refractive Surgery</title></titleInfo><titleInfo type="abbreviated"><title>JCRS</title></titleInfo><genre type="Journal">journal</genre><originInfo><dateIssued encoding="w3cdtf">199710</dateIssued></originInfo><identifier type="ISSN">0886-3350</identifier><identifier type="PII">S0886-3350(97)X8298-7</identifier><part><detail type="volume"><number>23</number><caption>vol.</caption></detail><detail type="issue"><number>8</number><caption>no.</caption></detail><extent unit="issue pages"><start>1127</start><end>1274</end></extent><extent unit="pages"><start>1247</start><end>1253</end></extent></part></relatedItem><identifier type="istex">35BA3EE3C6BD0A682E47B52C95A11C682D700F44</identifier><identifier type="DOI">10.1016/S0886-3350(97)80323-9</identifier><identifier type="PII">S0886-3350(97)80323-9</identifier><identifier type="ArticleID">80323</identifier><accessCondition type="use and reproduction" contentType="">© 1997American Society of Cataract and Refractive Surgery and European Society of Cataract and Refractive Surgeons.
