Purpose:
To describe this new technique to correct presbyopia with a corneal approach. P-CURVE consists of a prolate and aspheric shape of the cornea, which reduces in general spherical aberrations by causing less bending of light rays in the peripheral area of cornea as so to induce all rays to a single point of focus, and re-plans the distribution of some specific aberrations (negative spherical aberrations).
Setting:
ILMO - Istituto Laser Microchirurgia Oculare, Brescia, Italy
Methods:
LASIK technique is used to create an aspheric cornea in order to obtain prolate and aspheric curve in OU. It consists of a customization of the natural prolateness of the cornea to obtain far and near vision. It is a bilateral procedure and can treat hyperopes, myopes and emmetropes. The final curve is not multifocal but is a prolate and aspheric shape with the pre-planned flat area on the top of the curve. Nomograms, maps and 2 years results on 200 patients will be showed and discussed. RESULTS At 2 years post-op, results seem to be encouraging for the future as patients satisfaction postoperatively is remarkable. With this very smooth curve we eliminated glares, halos and night vision complaints, which are frequent in the multifocal cornea.
Conclusions:
Results and research in the field are optimistic about the new curve as a treatment for presbyopia. This is opening new solutions in order to fix presbyopia symptoms without complaints, with good vision quality and minimal loss of contrast sensitivity.
Additional follow-up data is needed to determine stability or effect.
