I did my Lasik at Hong Kong Laser Eye Center and the operation was quick and worth it. Side effects, for me, dry eyes and minor halo from lights at night. Makes driving a pain, but you get use to it. After the surgery had follow ups for 6 months.
Only problem was the scheduling for your followups. You may schedule for 11AM but wont be seen until 1 or 2 pm. The doctor I had was always late with these appointments, and the centre will schedule maybe 20 people at the same time as you. This isn't a problem as the followup takes maybe 2 minutes, but the doctor was always late for each one of my followups. I think he has to work in TST in the morning and go to Central in the afternoons, but still, do not expect to be done quickly with your followups.
