Optical Quality of the Eye with the Artisan Phakic Lens for the Correction of High Myopia

Abstract

Preliminary data using the Hartmann-Shack wavefront sensor have not revealed a tendency toward deterioration of the optical performance after the insertion of an Artisan lens for the treatment of high myopia. The Hartmann-Shack sensor was a useful tool for the objective assessment of the image optical quality of eyes with a phakic intraocular lens.

Changes in higher-order aberrations after implantation of a foldable iris-claw lens in myopic phakic eyes

“…The results in a study of rigid iris-claw IOLs in phakic eyes by Brunette et al 9 mostly confirm our findings; the Hartmann-Shack wavefront sensor did not detect a tendency toward deterioration in optical performance after IOL insertion. Overall, the mean postoperative RMS values for 3rd-order and 4th-order aberrations with a 3.0, 4.0, and 5.0 mm pupil were lower than preoperatively.…”

“…Although most studies of iris-fixated IOLs 3-7 have mainly addressed refractive outcomes, safety criteria, and complications after implantation, minor investigations 8,9 have focused on analysis of induction of HOAs.…”

Higher-order aberrations after implantation of iris-fixated rigid or foldable phakic intraocular lenses

“…Higher-order aberration, also referred to as irregular astigmatism, may influence postoperative visual outcomes and patient satisfaction and must be included in the preoperative evaluation and selection of refractive surgery candidates. [1][2][3] The literature contains several clinical studies of changes in HOA after refractive surgery for the correction of myopia, particularly after myopic laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK). [4][5][6][7][8][9][10][11][12][13] One study 4 reports that the amount of achieved correction was correlated with the changes in ocular HOA.…”

Five-year follow-up after anterior iris-fixated intraocular lens implantation in phakic eyes to correct high myopia

“…These intraocular operations retain the patients' clear lens, and thus the accommodation function is reserved; they maintain the original prolate shape of the cornea, as a result of which the optical qualities of the cornea are not altered. 3,4 Over the past few years, many kinds of refractive lenses have been implanted with success in phakic eyes to correct myopia, hyperopic, and astigmatism. 5,6 In 1986, Worst and Fechner modified the existing iris-fixated intraocular lens (IOL) into a negatively biconcave IOL with a convex-concave optic design.…”

“…16,17 This can increase coma and spherical-order aberrations and decrease contrast sensitivity. Implantation of iris-fixated IOLs has been shown to maintain optical performance, 4 also with the potential to improve contrast sensitivity. 18 Considering predictability, 93.2% of the eyes were within the ±1.0 D of the desired correction.…”
