Smile(small incision lenticule extraction) has almost replaced LASIK in developed country & got FDA approval but it still involves an incision to remove stromal tissue to induce refractive effect. Smile is approved upto 10D with up to 5D astigmatism. In smile also2.5_3mm incision is created by laser to use special smile forcep to go through incision to remove the lenticule, of course smile is best but corneal thickness assessment is must for long lasting results except few problems overlap throughout life. LASIK or smile operated eyes are not eligible for Rly ,air force & army jobs.
