Efficacité du presbyLASIK dans le traitement de l'hypermétrope presbyte : à propos de 56 cas

Abstract : To evaluate efficacy and safety of presbyLASIK on presbyopic hyperopes treated with Wavefront ALLEGRETTO excimer laser at the University Hospital of Guadeloupe (FWI). METHODS: This is a retrospective, monocentric study carried out at the University Hospital of Pointe-à-Pitre from September 2013 to April 2015. One hundred and twelves eyes of 56 patients who underwent a presbyLASIK with ALLEGRETTO WAVELIGHT excimer laser using a self-adapted nomogram were included. Patients had full hyperopic correction on dominant eye and mini-monovision with induced multifocality on non-dominant eye. Study parameters included mean uncorrected near and far visual acuity in pre-operatory, at 3 month, 6 month and the use of optical correction. Success of surgery was defined by a 0 logMAR far uncorrected visual acuity (FUVA) and a 0.18 logMAR near uncorrected visual acuity (NUVA). RESULTS: Mean FUVA was 0.53 logMAR ± 0.26, and NUVA was higher than 0.78logMAR preoperatively. Mean keratometry was 42.97 ± 1,8D ; Mean spherical equivalent was +2,02 ± 0,93D and mean astigmatism was -0,55 ± 0,33D. At 3 months FUVA was -0,045 logMAR ± 0.01 and a 0.21 logMAR ± 0.13 NUVA. At 6 months FUVA was -0.1 logMAR ± 0.09 and NUVA was 0.18 logMAR ± 0.07. The mean gain of line for FUVA was 6.09 ± 2.63. The success rate was 91% prior to any enhancement. CONCLUSION: PresbyLASIK is a method of choice in overcoming spectacle independence in presbyopic hyperopes. Self-adapted nomogram, based on mini-monovision and corneal multifocality on non-dominant eye, has shown safety and efficacy to provide comfortable viewing in daily activity.
