Iris-supported phakic lenses (rigid vs foldable version) for treating moderately high myopia: randomized paired eye comparison.

PURPOSE: To compare refractive performance of Artisan (Ophtec, Groningen, The Netherlands) or Verisyse phakic intraocular lens and its foldable version, Artiflex (Ophtec), for the correction of moderately high myopia. DESIGN: Randomized pilot study. METHODS: setting: Institutional practice. patient population: Thirty-one patients with myopia that ranged from -6 to -14 diopters (D). interventional procedure: One eye was implanted with an Artisan phakic intraocular lens (PIOL) and the other with an Artiflex PIOLs. main outcome measures: Primary outcome measure was the percentage of eyes with uncorrected visual acuity (UCVA) of >20/40 at one year after the operation. Main secondary outcome measures were the safety index, the change of two lines or more of best spectacle-corrected visual acuity (BSCVA) and the endothelial cell count. RESULTS: No intraoperative complications were noticed. One year after surgery, the percentage of eyes with UCVA of >20/40 was 51.6% (16/31 patients) for Artisan-treated eyes and 77.4% (24/31 patients) for Artiflex-treated eyes (P = .033). One month after surgery, this same percentage was 42.9% (13/31 patients) and 77.4% (24/31 patients), respectively (P = .004). The safety index at one year was 1.13 +/- 0.24 for Artisan-treated eyes and 1.12 +/- 0.21 for Artiflex-treated eyes, which is a difference that was not statistically significant (P = 0.742). At one year after surgery, the changes of two lines or more of BSCVA and the endothelial cell loss were similar for both groups. CONCLUSION: To correct moderately high myopia, the Artiflex lens provides a faster visual recovery and a better UCVA than does the Artisan lens. The safety of the lens should be supported by an enlarged sample size and a longer follow-up period.

Corneal ectasia after photorefractive keratectomy for low myopia.

OBJECTIVE: To alert ophthalmologists of the possibility of an aggravation of forme fruste keratoconus after photorefractive keratectomy (PRK). DESIGN: Clinical case report. INTERVENTION: Standard bilateral PRK for low myopia. MAIN OUTCOME MEASURES: Corneal topography, corneal thickness, and visual acuity. RESULTS: Corneal ectasia occurred bilaterally after PRK. Retrospective analysis of preoperative videokeratography indicated the existence of forme fruste keratoconus on the left eye. CONCLUSIONS: This article is the first case report of a bilateral corneal ectasia after PRK for low myopia. Even if there is no direct proof to demonstrate that PRK has worsened the evolution of keratoconus, the safety of the PRK procedure in forme fruste keratoconus must be considered.

A randomized paired eye comparison of two techniques for treating moderately high myopia: LASIK and artisan phakic lens.

OBJECTIVE: To compare refractive performance and safety of laser in situ keratomileusis (LASIK) and Artisan phakic intraocular lens (PIOL) for moderately high myopia. DESIGN: A prospective, randomized trial with paired eye control. PARTICIPANTS: Twenty-five patients with myopia ranging from -8.00 to -12.00 diopters (D). INTERVENTION: For each patient, one eye received LASIK and the other one was implanted with an Artisan phakic intraocular lens. The treated eye and the surgical technique were randomized. MAIN OUTCOME MEASURES: Primary outcome measure was spherical equivalent refraction. Main secondary outcome measures were the change of two or more lines and safety index (ratio postoperative to preoperative best-corrected visual acuity). RESULTS: One year after surgery, the mean spherical equivalent refraction was -0.74 +/- 0.67 D for LASIK-treated eyes and -0.95 +/- 0.45 D for Artisan-treated eyes, and the majority of LASIK-treated eyes (64%) and Artisan-treated eyes (60%) were within +/-1.00 D of the intended result. At 1 month, the mean spherical equivalent refraction was -0.28 +/- 0.71 D for LASIK and -1.07 +/- 0.59 D for Artisan (P < 0.01). The changes of two or more lines were in favor of Artisan (P < 0.05). The safety index was significantly better for Artisan (1.12 +/- 0.21) than for LASIK (0.99 +/- 0.17) at 1 year (P < 0.02). CONCLUSIONS: In cases of moderately high myopia, LASIK and Artisan phakic intraocular lenses seemed to produce a similar predictability. The best-corrected visual acuity and subjective evaluation of quality of vision were better for Artisan.
