For spectacle power removal.
The latest is ReLEx SMILE. (Small incision Lenticule extraction)
No blade related complications.
No flap related complications - flap dislocation, tear etc.
Painless - faster recovery.
Not long post op restrictions like no swimming, no eye make up, no rubbing the eye etc.
Corneal nerves cut 1/8th of LASIK.
Hence no dry eyes post op.
Bio mechanical strength of corneal maintained as the the top 100 microns have most densely packed collagen fibres and we do not disturb that layer as in LASIK.
Same time taken irrespective of the number to be corrected.
Higher numbers can be corrected.
