LASER SURGERY FOR GLAUCOMA
Selective laser trabeculoplasty (SLT) may be used to treat open angle glaucoma. It is a temporary solution, not a cure. Laser trabeculoplasty uses a "cold" (nonthermal) laser to stimulate drainage in the trabecular meshwork. SLT may be repeated three to four times.
Llaser peripheral iridotomy (LPI) may be used in patients susceptible to or affected by angle closure glaucoma. Laser energy is used to make a small opening in the iris to equalize the pressure between the front and back of the iris. Laser iridotomy reduces the risk of developing an attack of acute angle closure.
Months to years after cataract surgery, changes on the posterior capsule (which is left to suport the intraoculars lens) are observed. The posterior capsule shows sings of thickening, opacification and clouding. This can compromise visual acuity.
With the use of a laser, the capsule can be disrupt (Posterior Capsulotomy) clearing the central portion of the opacified lens capsule. This creates a clear central visual axis for improving visual acuity . This is a outpatient procedure.
