Status of toric intraocular lenses

Abstract

Toric intraocular lenses provide excellent vision for astigmatic cataract patients, and new designs are significantly improving visual acuity by minimizing the risk of rotation.

“…The percentage of patients with IOL rotation <10° on two similar to our 91.6%, varying between 96.7 and 100%. [1][2][3][4][5] In conclusion, Acrysof ® T3, T4 and T5 thoric lens implants allow the correction of presurgery astigmatism with a high percentage of success in what concerns NCVA and residual postsurgery astigmatism, with a minimum degree of lens axis rotation after 2-6 months according to the published series. [1][2][3][4][5][6] The minor of modification of the surgical procedure and a broad dissemination of the necessary presurgery diagnostic devices, many of which are mainstream, lead us to consider a higher degree of utilization of this type of lenses in the mid term for patients with significant presurgery astigmatism intervened for cataracts.…”

“…The clinical trial carried out by the US Food & Drug Administration (FDA) in 2005, prior to the marketing of Acrysof ® lenses, obtained 66% of patients with thoric IOL with NCVA≥ 0.8 at month six, similar to our 73.9%. 1 The different sample size could explain the difference (n=250; n=46) between both results. The lens implantation did not depart from the standard injection procedure of common lenses, with the main differences between the published studies being in the determination of the pre-op K values and the 0°-180° axis marking system.…”

“…These lenses have demonstrated excellent results in multicentre clinical trials since being presented in 1998, and their use has become mainstream in recent years. 1 This study analyses the results obtained in 54 patients intervened in our centre with implant of Acrysof ® thoric lenses (Alcon Laboratories, Inc., Fort Worth, Texas). Following the software IOL selection algorithm, the adequate IOL was determined for each patient and requested from the manufacturer.…”

Comparison between clinical outcomes of two different designs of toric multifocal intraocular lenses

“…[11][12][13] Today, toric lenses have been designed because such type of surgeries have been inadequate particularly in the cases with highdegree astigmatism and were proven to effectively correct corneal astigmatism. [14][15][16][17][18] In addition to eyeglass-free near vision provided by multifocal toric intraocular lenses manufactured recently for cataract cases with corneal astigmatism, it has been also possible to correct corneal astigmatism. Postoperative successful outcomes depend on certain factors in multifocal toric IOL implantation same as toric IOL implantation.…”

Noninsured services provided with insured cataract surgery in Canada: ensuring transparent and fair treatment for patients

“…Examples include aspheric, multifocal and accommodating intraocular lenses (specialfeature IOLs); astigmatism management; diagnostics, such as optical biometry; and imageguided femtosecond laser-assisted cataract surgery. Despite the impressive current standard of care for cataract surgery, these innovations may additionally enhance refractive outcomes 2 and reduce a patient's need for corrective lenses -but at a financial cost.…”
