Brief Summary
Nd-YAG Laser for changing iris coloration by the principle of depigmentation for cosmoses Is that procedure safe or not a prospective study
Detailed Description
Nd-YAG Laser for changing iris coloration by the principle of depigmentation for cosmoses Is that procedure safe or not a prospective study safety will be assessed by measuring IOP using Goldman applanation tonometry pre and post-session.
visual acuity assessment in Log-Mar pre and post-session. Refraction assessment pre and post-session. Lens and fundus assessments on slit-lamp and using auxiliary lens 78D

Outcomes
Primary Outcomes
Monitoring intra-ocular pressure (IOP) by the standard Goldman applanation tonometer before and after ND-YAG Laser for iris depigmentation
Time Frame: one year
Session of Nd-YAG Laser targeting the iris using power less than that used for peripheral iridotomy causing pigment bleaching to change the iris colour for cosmoses, which may cause pigmentary glaucoma (secondary open angle glaucoma).
Safety of ND-YAG Laser, by visual acuity assessment in log-mar subjectively by using Snellen chart before and after ND-YAG Laser
Time Frame: one year
If ND-YAG LASER could affect visual acuity.
Secondary Outcomes
No secondary outcomes reported
