Evaluation of the Rayner T Toric Centerflex IOL to correct high astigmatism
Presented at the meeting of the Korean Ophthalmic Society, October, 2004 Evaluation of the Rayner 571T Toric Centerflex IOL to correct high Astigmatism Also presented at ESCRS, Paris, France, September 2004 First Experiences with the Rayner (571T) Toric IOL Auffarth G.U., Rabsilber T.M., Reuland A., Limberger I-J. Heidelberg, Germany. Purpose: Astigmatism over 3 D can hardly be corrected completely using special cut techniques or sutures during cataract surgery. Therefore, the implantation of an individually manufactured toric IOL is a good alternative. Patients and Method: At the Department of Ophthalmology, Universitity of Heidelberg, Germany, we implanted the Rayner toric IOL (model: 571T) in 9 eyes of 6 cataract patients (47 to 71 years old). Results: The preoperative refraction was between –3.25 and +4.0 D (sphere) and between –6.75 and –2.0 D (cylinder) respectively. The lens power ranged between 6.5 and 21.5 D (sphere) and between 2.0 and 10 D (torus) respectively. Three months postoperatively, the patients achieved a mean UCVA of 20/50 and BCVA of 20/32 (range 20/40 to 20/20). By comparing the target refraction with the spherical equivalent, we calculated a mean difference of only 0.5 D. Postoperatively, remaining cylinder values between 0.5 and 3 D were evaluated. Discussion: The Rayner toric IOL showed good functional results as well as a stable position in the capsular bag with only low scores for decentration and rotation.
