5-Year Prospective Follow-Up of Artisan Phakic Intraocular Lenses for the Correction of Myopia, Hyperopia and Astigmatism

Abstract

Aim: To determine the efficacy and safety of Artisan phakic intraocular lenses (IOLs) for refractive error correction. Methods: A prospective study was conducted on patients undergoing Artisan phakic IOL implantation for myopia, hyperopia or astigmatism from 2002 to 2008. Visual acuity, manifest refractive spherical equivalent (MRSE), endothelial cell counts and higher order aberrations were recorded pre- and postoperatively. Results: One hundred and fifty-one (84 patients) myopic (mean MRSE –11.2 ± 4.1 D) and 14 (7 patients) hyperopic eyes (mean MRSE 7.1 ± 1.3 D) were treated. Twenty eyes (11 patients) had toric IOLs to correct astigmatism (mean MRSE –9.05 ± 6.13 D, mean astigmatism 4.06 ± 1.26 D). Three months postoperatively, mean MRSE in 37.6% of eyes was within ±0.5 D, 61.8% within ±1.0 D and 91.4% within ±2.0 D. 18.5% underwent keratorefractive surgery to correct residual refractive error. A 1.56-fold increase occurred in 4th order spherical aberration. Endothelial cell loss was 1.45% at 1 year and negligible at 5 years. Fifty-four eyes (29.2%) gained one or more lines of best corrected visual acuity and no eye lost a line. Conclusion: Artisan phakic IOLs are safe and effective for refractive error correction.

Iris-fixated toric phakic intraocular lens for myopic astigmatism

“…However, the rigid Artisan toric pIOL has been extensively studied. [3][4][5][6][7][8][9][10][11][12][13][14] In a European multicenter clinical study, Dick et al 4 found no loss of CDVA and a gain of 1 or more lines from the preoperative CDVA in 65.7% of eyes; in 88.6% of eyes, the UDVA was 20/40 or better. The spherical and astigmatic errors were significantly reduced in all cases.…”

Correction of myopic astigmatism with a foldable iris-claw toric phakic intraocular lens: Short-term follow-up

“…The Artisan concept has stood the test of time for its iris-claw fixation principle as well as the clinical long-term safety and efficacy results. [2][3][4]6,12,13 These results have been well documented for the spherical Artiflex IOL and have been compared with those of its predecessor, the rigid (PMMA) Artisan IOL. 9,[14][15][16][17] The foldable Artiflex toric pIOL has 2 main advantages over the rigid Artisan toric type.…”

Toric collagen copolymer phakic intraocular lens to correct myopic astigmatism in eyes with pellucid marginal degeneration

“…10,11 The toric Implantable Collamer Lens collagen copolymer phakic intraocular lens (pIOL) (Staar Surgical Co.) has been used to safely and reliably correct moderate to high myopia and astigmatism. [12][13][14][15][16] Given that the progression of corneal thinning and ectasia in PMD, like keratoconus, tends to stabilize in the third or fourth decade of life, 17 toric pIOL implantation may be another option for the surgical correction of myopic astigmatism in this setting. Studies [18][19][20] are beginning to show the safety and efficacy of this treatment modality in keratoconus.…”

“…Toric Implantable Collamer Lens pIOLs have been validated in many studies as safe and effective for the correction of moderate to high myopic astigmatism. [12][13][14][15][16] Randomized prospective comparisons between toric pIOL implantation and excimer laser vision correction 24,25 show better safety, predictability, and stability profiles with pIOLs. Based on these studies, surgeons are now using toric pIOLs to successfully treat myopic astigmatism in keratoconus and keratoconus-suspect eyes.…”
