laser capsulotomy

laser capsulotomy

The use of a laser to make a hole in the capsule surrounding the lens of the eye to let light pass. Extracapsular removal of a cataract allows the capsule surrounding the lens to remain in the eye; however, if the capsule becomes cloudy, laser capsulotomy is used to restore vision.

Twelve (63.2%) of the eyes developed posterior capsule opacification and underwent Nd:YAG laser capsulotomy. Payne et al.
Methods: In an institution, 65 eyes of 65 consecutive pseudophakic patients with posterior capsule opacification underwent Nd:YAG laser capsulotomy. The patients were divided into two groups according to the IOL type.
Evaluation of IOP is done before laser procedure and after the laser capsulotomy procedure at 1 h, 4 h, and 24 h.
After 3 years of follow-up, they found significantly less PCO and lower Nd:YAG laser capsulotomy rates in the eyes implanted with the hydrophobic IOL than in the plate-haptic silicone IOL group.
Femtosecond laser capsulotomy and manual continuous curvilinear capsulorrhexis parameters and their effects on intraocular lens centration.
In the present study 30% had clinically significant PCO, Nd-YAG laser capsulotomy was performed in 17.5% of cases and one (2.5%) patient had very thick PCO which was resistant for Laser; in this patient surgical membranectomy was done at an interval of 4 months after surgery which matches with study of Eckstein M et al [18] in which Nd-YAG laser capsulotomy was performed in 63.46%, more than one laser session required in 11.53% and surgical membranectomy was done in 17.3%.
Conclusion: Nd:YAG laser capsulotomy is safe, effective and convenient method for treatment of posterior capsular opacification.
Patients and Methods: The study was conducted on consecutive aphakic and pseudophakic patients suffering from posterior capsular opacification who were admitted for Nd-YAG laser capsulotomy at Ophthalmology Department of Saidu Teaching Hospital, Saidu Sharif, Swat, from November 2006 to May 2007.
However, Nd:YAG laser capsulotomy can cause certain complications, like cystoid macular edema, retinal detachment and elevation of intraocular pressure (IOP) after the procedure, which can be significant and can result in irreversible visual loss7.
Posterior capsulotomy combined with anterior vitrectomy was not performed in 4 children <5 years old who were cooperative enough to undergo Nd:YAG laser capsulotomy. The incisions were closed with 10-0 nylon sutures.
Exclusion criteria included lack of follow-up beyond 21 days postoperatively, concurrent ocular conditions limiting best corrected distance visual acuity to less than or equal to 20/40 Snellen, visually significant posterior capsular opacification (PCO) requiring YAG laser capsulotomy within 4 months of phacoemulsification, or visually significant dysphotopsia requiring IOL exchange.
