Titel | Multifocal ablations in myopic patients using the wavelight Allegretto wave excimer laser: preliminary results |
Abstract Nr. | A2029 |
Doel | To assess the quality of the visual results in myopic patients older than 45 years that underwent a bilateral LASIK treatment using a multifocal ablation profile. |
Methodes | In this prospective study 15 presbyopic myopic patients underwent a bilateral LASIK in which the initial shortsightedness was overcorrected by 1.50 dioptre and subsequently retreated by a hyperopic treatment of +1.50 dioptre. The optical zone was 6.5 mm, both treatments were centered on the pupil by means of the eye tracker. The resulting ablation profile is intended to have multifocal characteristics. After 2 months the monocular and binocular UCVA and BCVA in distance and near vision were recorded. Conventional and elevation topographies, contrast sensitivity measurements and wavefront-analysis using Ray-tracing technology were performed before and after surgery. A subjective questionnaire was submitted to the patients. |
Resultaten | The mean age of the population group was 52 years, mean follow-up 3 months. The superposition of the myopic and hyperopic treatments results in an array-like multifocal ablation profile and in an increase of the corneal asphericity. The mean UCVA in distance was 1.0, the mean UCVA in reading Parinaud 3. Only 15% of the patients lost 1 line of BCVA. Patient satisfaction was high. |
Conclusie | In this small scale preliminary study both surgeon and patients were happily surprised by the good results obtained in distance and near vision when presbyopic myopic patients underwent a bilateral multifocal centered LASIK treatment. |
