At his offices in Poughkeepsie & Fishkill he provides LASIK in New York, Custom LASIK and All Laser LASIK Surgery in New York as well as other types of Laser Eye Surgery. Dr. Modi's frequent lectures and course presentations have resulted in his being recognized internationally as an Ophthalmic Surgeon with expertise in Cataract Surgery in New York and Lens Implants including presbyopia correcting intraocular lenses (IOL) such as ReStor and Crystalens in addition to LASIK Eye Surgery in New York. He completed his Clinical Training in Ophthalmology at the Albert Einstein College of Medicine in New York. In addition Dr. Modi continues to serve as an Assistant Clinical Professor of Ophthalmology at Albert Einstein College of Medicine in New York. Dr. Modi has been providing Laser Eye Surgery in New York with the Excimer Laser for Laser Vision Correction since its approval since 1995 and has been performing Laser Eye Surgery procedures including LASIK, Lasik Eye Surgery, Custom LASIK and other Laser Vision Correction procedures in the Hudson Valley region of New York since 2002.
A host of methods to treat lens tilt and Z syndrome with Nd:YAG laser have been postulated. Treatment typically centers on trying to relieve tension behind the anteriorly vaulted haptic by performing a small oval capsulotomy between the hinge and the insertion of the hinge loops, taking care to lyse any fibrotic bands that are present. It is important to avoid extending the capsulotomy past the edge of the optic to avoid anterior migration of the vitreous. If this is insufficient, a small noncontiguous central capsulotomy can be done. If this is also insufficient, a small oval capsulotomy behind the posteriorly vaulted haptic can also be performed.

For many applications, the infrared light is frequency-doubled or -tripled using nonlinear optical materials such as lithium triborate to obtain visible (532 nm, green) or ultraviolet light. Cesium lithium borate generates the 4th and 5th harmonics of the Nd:YAG 1064 nm fundamental wavelength. A green laser pointer is a frequency doubled Nd:YVO 4 diode-pumped solid state laser ( DPSS laser ). Nd:YAG can be also made to lase at its non-principal wavelength. The line at 946 nm is typically employed in "blue laser pointer" DPSS lasers, where it is doubled to 473 nm.
