Nd:YAG Laser Capsulotomy: Efficacy and Outcomes Performed by Optometrists.

ABSTRACT:

Significance

An increasing number of optometrists are performing Nd:YAG laser capsulotomy procedures; however, there is limited published information on the outcomes of these procedures.

Purpose

This study aimed to assess the efficacy and safety of capsulotomy procedures performed by optometrists.

Methods

Subjects diagnosed with posterior capsule opacification causing reduced vision and subjective visual complaints were recruited for this study. A baseline examination was performed to ensure that the subjects met all the necessary criteria. The procedure was performed by a licensed doctor of optometry at six different clinics, and each subject was monitored for visual outcome and any potential complications.

Results

Subjects' Snellen visual acuity improved from an average of 20/40 to 20/23 ( P < .001) with no complications of increased intraocular pressure, inflammation, visually significant lens pitting, macular edema, or retinal detachment. Of 78 subjects who responded to a post-procedure survey, 77 (99%) reported subjective improvement in vision after capsulotomy.

Conclusions

Based on the outcomes of this study, YAG laser capsulotomies are effective treatments to improve patient vision that can be safely and effectively performed by optometrists.

Project description:BackgroundThe vitreous is the clear jelly of the eye and contains fine strands of proteins. Throughout life the composition of this vitreous changes, which causes the protein strands in it to bundle together and scatter light before it reaches the retina. Individuals perceive the shadows cast by these protein bundles as 'floaters'. Some people are so bothered by floaters that treatment is required to control their symptoms. Two major interventions for floaters include Nd:YAG laser vitreolysis and vitrectomy. Nd:YAG laser vitreolysis involves using laser energy to fragment the vitreous opacities via a non-invasive approach. Vitrectomy involves the surgical replacement of the patient's vitreous (including the symptomatic vitreous floaters) with an inert and translucent balanced salt solution, through small openings in the pars plana.ObjectivesTo compare the effectiveness and safety of Nd:YAG laser vitreolysis to pars plana vitrectomy for symptomatic vitreous floaters.Search methodsWe searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2016, Issue 12), MEDLINE Ovid (1946 to 17 January 2017), Embase Ovid (1947 to 17 January 2017), LILACS (Latin American and Caribbean Health Sciences Literature Database) (1982 to 17 January 2017), the ISRCTN registry (www.isrctn.com/editAdvancedSearch); searched 17 January 2017, ClinicalTrials.gov (www.clinicaltrials.gov); searched 17 January 2017 and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en); searched 17 January 2017. We did not use any date or language restrictions in the electronic searches for trials. We also searched conference proceedings to identify additional studies.Selection criteriaWe included only randomised controlled trials (RCTs) that compared Nd:YAG laser vitreolysis to pars plana vitrectomy for treatment of symptomatic floaters.Data collection and analysisWe planned to use methods recommended by Cochrane. The primary outcome we planned to measure was change in vision-related quality of life from baseline to 12 months, as determined by a vision-related quality of life questionnaire. The secondary outcomes we planned to measure were best corrected logMAR or Snellen visual acuity at 12 months for the treated eye(s) and costs. Adverse outcomes we planned to record were the occurrence of sight-threatening complications by 12 months (asymptomatic retinal tears, symptomatic retinal tears, retinal detachment, cataract formation, and endophthalmitis).Main resultsNo studies met the inclusion criteria of this review.Authors' conclusionsThere are currently no RCTs that compare Nd:YAG laser vitreolysis with pars plana vitrectomy for the treatment of symptomatic floaters. Properly designed RCTs are needed to evaluate the treatment outcomes from the interventions described. We recommend future studies randomise participants to either a Nd:YAG laser vitreolysis group or a vitrectomy group, with participants in each group assigned to either receive treatment or a sham intervention. Future studies should follow participants at six months and 12 months after the intervention. Also they should use best corrected visual acuity (BCVA) using an Early Treatment of Diabetic Retinopathy Study (ETDRS) chart read at 4 metres, vision-related quality of life (VRQOL), and adverse outcomes as the outcome measures of the trial.

Project description:ImportanceProtective eyewear or corneal shields are recommended during cosmetic facial laser treatment.ObjectiveTo describe the occurrence of corneal inlay damage following treatment to the eyelids and face with an Nd:YAG laser.Design, setting, and participantsThis observational case report includes a single incident case cared for at a tertiary care center. A 58-year-old man who had undergone bilateral uncomplicated myopic laser in situ keratomileusis surgery in 2003 and corneal inlay implant in the nondominant left eye in 2013 experienced decreased visual acuity (VA) and pain in the left eye after the application of 2 passes of the Nd:YAG laser to his face and both eyelids for facial tightening. At presentation, the uncorrected VA was counting fingers OS and 20/20 OD. Slitlamp biomicroscopy showed a corneal epithelial defect overlying a deformed corneal inlay, peripheral scattered pigmentary deposits, corneal haze, and brown discoloration of the lamellar pocket of the inlay. He underwent explant of the inlay and debridement 48 hours later because of deteriorating VA and increasing corneal haze.ExposureApplication of long-pulsed Nd:YAG laser at 1064 nm to the middle one-third of both upper eyelids and the periorbital region in a man with a corneal inlay implant. Corneal shields were not worn during the procedure. The peak penetration depth of this laser system is approximately 4 mm. The mean (SD) thickness of the upper eyelid in Asian eyes is 1.127 (0.238) mm.Main outcomes and measuresImprovement of corneal inlay damage.ResultsIn this 58-year-old man, 3 months after the inlay explant, the intrastromal discoloration had resolved. There was still residual corneal haze, but the patient was able to achieve a best-corrected VA of 20/25 OS for distance and J3 (Snellen equivalent, 20/30) OS for near.Conclusions and relevanceAlthough the exact cause and effect cannot be determined from a single case, our findings suggest that a history of corneal inlay implant should be asked about prior to any long-pulsed Nd:YAG laser treatment to the periorbital skin and eyelids. Furthermore, these findings suggest that laser treatment to the eyelids should be avoided and that protective eyewear or corneal shields are recommended during cosmetic facial laser treatment in all patients.
