YAG Lasers for Trabeculotomy and Capsulotomy

YAG lasers are often used for Capsulotomy and Trabeculectomy procedures. Yag Laser Capsulotomy is a procedure intended to correct posterior capsule opacity whereas Trabeculectomy is a procedure used in Glaucoma patients to relieve intraocular pressure via YAG laser. A Capsulotomy is necessary when the capsule becomes cloudy because of healing scar tissue. This is a fairly common condition post-operatively. The Yag Laser creates a tiny hole in the posterior membrane to allow the passage of light through and to restore clear and unobstructed vision. A Trabeculectomy or SLT (Selective Laser Trabeculectomy) is partial removal of the trabecular meshwork and surrounding areas to drain excess fluid and relieve pressure.

Many YAG lasers on the market now boast the dual features that enable an Ophthalmologist to perform both Capsulotomy and Trabeculectomy procedure via one laser. This allows an Ophthalmology practice to utilize available space and decrease the amount of large equipment needed. Many of these YAG lasers offer upgradable features that are available to add on at a later date, insuring your practice stays up to date.
