Rangaswamy Srinivasan (born February 28, 1929, in Madras, India [1]) is a physical chemist and inventor with a 30-year career at IBM Research.He has developed techniques for ablative photodecomposition and used them to contribute to the development of LASIK eye surgery.
Refractive surgery is an optional eye surgery used to improve the refractive state of the eye and decrease or eliminate dependency on glasses or contact lenses. This can include various methods of surgical remodeling of the cornea ( keratomileusis ), lens implantation or lens replacement.
One conspicuous difference between SMILE and LASIK is the size and shape of the corneal incision. In LASIK, the surgeon performs a 270-degree, 20 mm long incision, while in SMILE the so-called "side cap cut", which is the incision through which the surgeon extracts the lenticule, is usually about 4 mm long.

Laser Blended Vision can be achieved through laser eye surgery, usually performed as LASIK, although surface laser eye surgery PRK or LASEK can be used to produce the effect. Laser Blended Vision works by increasing the depth of field of each eye through subtle changes in the optics of the corneal spherical aberration . [ 2 ]
LASIK can correct myopia up to -12 to -14 D. The higher the intended correction the thinner and flatter the cornea will be post-operatively. For LASIK surgery, one has to preserve a safe residual stromal bed of at least 250 μm, preferably 300 μm. Beyond these limits there is an increased risk of developing corneal ectasia (i.e. corneal ...

Phakic IOL appear to be lower risk than excimer laser surgery (LASIK) in those with significant nearsightedness. [9] More commonly, IOLs are implanted via Clear Lens Extraction And Replacement (CLEAR) surgery, also known as refractive lens exchange (RLE) [10] or clear lens extraction (CLE). During CLEAR, the crystalline lens is extracted and an ...
