BARCELONA Long-term results with up to 4 years follow-up show that the LaserACE presbyopia correction procedure can restore accommodation in a safe, effective and stable manner, according to a surgeon speaking here.
Patients regain 2 D to 3 D of accommodation and do not appear to lose [it] over time, Dimitrii Dementiev, MD, said at the winter meeting of the European Society of Cataract and Refractive Surgeons.
The procedure uses a 2.94 µm Er:YAG laser to create 600 µm microexcisions that lead to the decompression of connective tissue in three critical zones of the sclera. This simple and minimally invasive approach restores the physiological conditions necessary for the accommodative process, he said.
In an international, multicenter clinical trial, 64 eyes of 32 patients aged 42 to 69 years were treated with the LaserACE surgical procedure. Dr. Dementiev showed that 89% of the patients were able to read J3 or better, and 81% were J2 or better without reading spectacles. In addition, 95% were J5 and 85% were J3 for intermediate vision.
On the whole, 78% of the patients were spectacle-independent for near and 98% were spectacle independent for intermediate, he said.
All patients achieved some improvement in both quality and quantity of visual performance. Follow-up also showed a statistically significant suppression of presbyopia progression.
No major complications were reported, Dr. Dementiev noted.
