Abstract Details



Purpose:

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.

Setting:

Single surgeon, single center, prospective case series

Methods:

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

Results:

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.

Conclusions:

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.
