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
