• Objective: to assess the safety and effectiveness of the platform CustomCornea from Alcon for wavefront-guided customized treatments of myopia and astigmatism.

  Setting: Instituto Oftalmológico Amigó y Muiños. Tenerife. Spain.

  Material and methods: this prospective study was performed over a series of 98 consecutive myopic eyes with or without astigmatism, with a spherical equivalent (SE) up to ¿6.62 diopters (D) and a cylindrical component up to 3.75 D. Myopia (SE) was mild (-< ¿2.50 D) in 27 eyes, moderate (> ¿2.50 and -< ¿6.00 D ) in 40 eyes and severe (> ¿6.00 D) in 2 eyes. All treatments were performed by using a fixed optic zone of 6.5 mm with a transition zone of 1.25 mm. Visual acuity, subjective refraction, complications and adverse reactions were measured up to three months after the surgery.

  Results: Results at the third post-operative month were obtained from 69 eyes. Uncorrected visual acuity (UCVA) was 20/20 or better in 94 % of eyes with mild myopia (n=27), in 78% of eyes with moderate myopia (n=40) and in 100% in eyes with severe myopia (n=2). Mean SE refraction improved to +0.29 D ±0.33 (¿0.37\+0.88). Five eyes (8%) lost one line of best corrected VA (BCVA) and no eye lost two or more lines of BCVA. Eighteen eyes (26%) improved one line of BCVA. Efficacy index (postoperative UCVA/preoperative BCVA) was 0.88 ± 0.16 (range 0.74\1.2). Safety index (mean postoperative BCVA/mean preoperative BCVA) was 1.02 ± 0.07 (range 0.83\1.2).

  Conclusions: eyes treated with CustomCornea for mild and moderate myopia with with or without astigmatism up to 3.75 D, showed good visual results with no correction, non significant loss of BCVA and improvement over conventional LASIK as measured by significant improvement in BCVA, safety and efficacy indexes.
