Secondary Artisan-Verysise aphakic lens implantation.

PURPOSE: To evaluate efficacy, predictability and safety of Artisan-Verysise intraocular lens (IOL) secondary implantation for aphakia correction. SETTING: Instituto de Microcirugía Ocular, and Autonoma University of Barcelona, Barcelona, Spain. METHODS: Uncorrected visual acuity, best spectacle-corrected visual acuity (BSCVA), manifest refraction, endothelial cell count, and clinical complications were evaluated. Sixteen consecutive eyes of 14 patients with aphakia were submitted to surgery. Postoperative examinations were done at 6 weeks, 6 months, 1 year, and every year for at least 3 years. An iris-supported Artisan-Verysise IOL was implanted for aphakia correction. RESULTS: Thirty-six months after Artisan-Verysise lens implantation, BSCVA was 20/40 or better in 6 eyes (37.5%). Preoperatively, 5 eyes had the same BSCVA (31.25%). Mean postoperative spherical equivalent (SE) was 0.46 diopter (D). Mean endothelial cell loss was 10.9% 36 months postoperatively. The cell loss occurred predominantly during the first year (7.78%). Cystoid macular edema was observed in 2 cases, 1 of them associated with chronic unresponsive low intraocular pressure. No other serious complications were observed. CONCLUSION: Artisan-Verysise IOL implantation seems a safe, predictable, and effective option for aphakic eyes without capsule support.

Phaco rolling technique.

We describe a phacoemulsification technique for soft and medium-hard cataracts to decrease phaco time and enhance the safety of the procedure. After conventional hydrodissection and hydrodelamination are performed, a 15- or 30-degree phaco tip is positioned on the peripheral lens beside the capsulorhexis edge and in contact with the nucleus-epinucleus interface. The lens is then aspirated onto the phaco tip. Phacoemulsification is started with the ultrasound energy level limited to 15% to 25% depending on the nuclear hardness and with linear aspiration power up to 250 mmHg. The phaco tip is slightly displaced to the vertex of the pupil to keep it occluded, and the lens is rotated. The phaco tip is placed in the same area and a modified manipulator used to keep the lens in a horizontal position during rotational movement. The small, hard, central nucleus is usually emulsified at the end.

A review of suturing techniques for posterior chamber lenses.

PURPOSE OF REVIEW: To evaluate the outcome of last the 15 years' experience with the transscleral suture fixation technique of posterior chamber intraocular lens (PC IOL). RECENT FINDINGS: The implant of an anterior chamber IOL, especially the iris-claw lens, is safer and a better option than the transsclerally fixed IOL. SUMMARY: After bibliographic review of anterior chamber lenses implant results with transscleral fixation, we conclude that the number of complications is less in the iris fixation lens.

Artisan toric phakic intraocular lens for the correction of high astigmatism.

PURPOSE: To evaluate efficacy, predictability, and safety of Artisan toric phakic intraocular lens (Ophtec, Groningen, The Netherlands) implantation for the correction of astigmatism higher than 2 diopters. DESIGN: Interventional case series. METHODS: This prospective study included 27 eyes of 16 patients with a mean preoperative spherical equivalent of -11.78 +/- 6.24 diopters and a mean preoperative astigmatism of -3.43 +/- 0.81. The Artisan phakic intraocular lens was inserted in the anterior chamber through a posterior corneal incision; the technique is similar to the implantation of the classical Artisan lens, but in these cases it is particularly important to secure the lens accurately in the correct axis. The main parameters evaluated in this study were uncorrected visual acuity, best-corrected visual acuity, refraction, and endothelial cell count. RESULTS: Twelve months after the implantation of the Artisan toric phakic intraocular lens, 62.90% of the eyes were within +/-0.50 diopters. of emmetropia and 96.20% within +/-1.0 diopters. Seventy percent of the eyes gained 1 or more Snellen lines from their preoperative best-corrected visual acuity, and 11.11% lost 1 Snellen line. Mean endothelial cell count increased 2.9%. Mean of the parallel and orthogonal components of cylinder correction were 1.97 diopters and 0.10 diopters, respectively, of the intended cylinder change. The mean of axis alignment error was 10.53 degrees. No serious complications were observed. CONCLUSION: Artisan toric phakic intraocular lens implantation appears to be a safe and predictable method for the correction of high levels of astigmatism.
