Complications of laser vitreolysis

Scott Geller MDFeikeGerbrandy MD

Fort Myers, Florida Amsterdam, Netherlands

In spite of two decades of reports of successful outcomes for laser vitreolysis, the Ophthalmic community has been slow to adopt this treatment modality, in part due to lack of large clinical studies of complication rates.

We reviewed the medical records of 3 Ophthalmologists who performed laser vitreolysis during the year 2011 on 542 eyes of 502 patients.

  • Surgeon 1 (SG)

  • 25 years experience

  • LASAG Microruptor II YAG

  • 691 sessions

  • 219 patients

  • 232 eyes average

  • 4.7 mJ/pulse

  • 435 p/session

  • Surgeon 2 (JK)

  • 12 years experience

  • Ellex YAG

  • 308 sessions

  • 140 patients

  • 140 eyes average

  • 8.0 mJ/pulse

  • 150 p/session

  • Surgeon 3 (FG)

  • 3 years experience

  • Zeiss Visulase YAG

  • 302 session

  • 143 patients

  • 170 eyes average

  • 6.8 mJ/pulse

  • 378 p/session

Complications of Laser Vitreolysis

OBSERVED COMPLICATIONS

  • 3 eyes elevated IOP (>30) 1 phakic, 2 pseudophakic; 7050 mJ total average engergy

  • 2 patients (1 phakic, 1 pseudophakic) returned to normal IOP after 5 months medical therapy

  • 1 patient required cyclodialysis surgery after 2 months unsuccessful (IOP 36) medical therapy

  • 3 eyes elevated IOP(2phakic, 1 pseudophakic), 12419 mJ total average energy

  • 2 eyes retinal hematoma with no visual sequelae (1 eye had BRVO 3.5 months post laser)

  • 1 eye retinal tear 2 weeks post laser 2 sessions 2729 mJ 806 pulses

  • 1 eye presumed lens opacity unconfirmed by a second ophthalmologist

CONCLUSION

Experienced surgeons have a very low complication rate

Retinal detachment is NOT a significant issue with laser vitreolysis

Elevated intraocular pressure is a major concern, more so with high power/pulse settings in pseudophakes

Safety of Floaterlaser or YAG vitreolysis, the learning curve of 500 eyes

Complicaties van eerste 150 ogen (1) vergeleken met volgende 350 ogen(2):

Groep 1: direct complications 2.6%

3x retinal hit

1x traumatic cataract

late adverseevents: 1x retinaldetachment (0,66%),

1x elevated IOP (0,66%).

Groep 2: direct complications 0%

0x retinal hit

0x traumatic cataract

late adverseevents: 2x retinaldetachment (0,57%)

4x elevated IOP (1,14%)

Conclusie: YAG vitreolysis heeft laag risico indien uitgevoerd door een ervaren oogarts. Er is een lange leercurve. Dit pleit ervoor dat floaterlaser als subspecialisme door een beperkt aantal ervaren oogartsen moet worden uitgevoerd.

Oogdrukstijging staat los van ervaring.

Background:

Floaterlaser, YAG vitreolysisornebulotrypsia is a laser treatment of vitreous floaters. Worldwidethere are only a handfull of ophthalmologistsable to performthistreatment. Theyfounded the International Society of Vitreous Laser Surgery (ISVLS).

The members of the ISVLS cooperate in research and treatmentprotocols.

Feike Gerbrandy starteddoing floaterlaser in 2009. Sincethenhe has treatedabout 750 eyes

In a recent studybyhis team (submittedforpublication)about 86% of patients are satisfiedwith the result.

These data show that most disturbingfloaters canbesuccesfullytreatedby laser.

As withmanytreatments: after the pioneers have showed the wayfollowerswillcome: more ophthalmologistswill want to learn floaterlaser.

Evaluation:

In the first 150 eyes the lens or retina was hit in 2.6% of eyes, versus 0% in the following 350 eyes.

Thisclearlyillustrates the learning curve of thistechnique.

Conclusion: Floaterlaser of YAG vitreolysisornebulotrypsia is a low risk and safe procedure ifperformedbyanexperiencedophthalmologist. The patientdemandforthis procedure is increasing.
