Purpose • To evaluate the accommodative range of the NuLens AIOL in 5 patients and to study its behavior and biomechanics in 5 eyes implanted by one experience surgeon (L. Izquierdo) at Oftalmosalud Eye Institute Lima-Peru.
Material and Methods • Material and Methods: 5 eyes of patients range between 27 and 65 years old, 4 women and 1 men, with normal anterior chamber and no corneal pathology who had impaired vision in one eye due to amblyopia (4 high myops and 1 cataract patient).
Material and Methods • Pre-surgical examination: Biomicroscopy, IOL master, UBM, Visante-OCT were done to all patients. • A perfect 5.5 mm continuous circular capsulorrhexis normal Phacoemulsification was performed; the NuLens AIOL was implanted in 2 steps. First the Base of the Lens and secondly, the Haptic of the IOL. • An endoscopic revision of the incision of the zonule was examined by Dr. Joshua Ben-nun at the operating room.
Results • Pre-Implantation values: sphere (media -5.60), cylinder (media -2.55), axis (media 52.00), LogMar BCVA (media 0.6520) and near VA at 40cm (media 12.25). • Post-Implantation values: sphere (media -0.45), cylinder (media -2.50), axis (media 73.80), LogMar BCVA (0.7380) and near VA at 40cm (media 14.50). • Accommodative range: 6.00 Diopters. p=0.0000 (See Table).
Results Results of accomodative range of NULENS (AIOL)
Conclusions • This is a new technology which seems to be an alternative in the future to achieve more accommodative range and therefore a better quality of vision. We are still working in adjusting the power of the AIOL and its size to improve its biomechanics inside of the eye. • NuLens demonstrated to have an accommodative range of 6 Diopters in all patients studied so far and a central positioning without damaging any anterior and posterior chamber structures of the eye.
Conclusions • We are demonstrating our preliminary results in 5 patients after 15 days average after AIOL implantation. • Far VA has demonstrated a significant improvement even though 4 out of the 5 patients with amblyopia were high myopic (N=5). At the moment, near VA has not been determined accurately due to cyclopegic status of the 5 patients.
