Abstract Details


In the literature there are no reports about safety and efficacy of floater laser. The author has prospectively followed all treated cases. This has resulted in a large prospective case series.


Single surgeon, single center, prospective case series


The learning curve was assessed by comparing the direct complications of the first 150 eyes (group 1) to the following 350 eyes (group 2).


Group 1: direct complications 2.6% (3x retinal hit, 1x traumatic cataract), late adverse events: 1x retinal detachment (0,66%), 1x elevated IOP (0,66%). Average numer of shots 527, average of 1.49 treatments per eye. Patient with elevated IOP received 2892 shots. No cases of (severe) visual loss. Group 2: direct complications 0% (0x retinal hit, 0x traumatic cataract). late adverse events: 2x retinal detachment (0,57%), 4x elevated IOP (1,14%). Average number of shots 657, average number of treatments. Patients with elevated IOP received 2926,3707,714 and 550 shots respectively. No cases of (severe) visual loss.


Conclusion: YAG vitreolysis has a low risk profile. For direct complications there is a significant learning curve. The 0.6% rate of retinal detachment is very low. Floaters-only-vitrectomy has reported rates of retinal detachment of 2.5% to 10.9% and 2.6% severe visual loss/blindness. Elevated eye pressure is a concern independent of experience. There is a relation between IOP and the number of shots.
