Our Experienced Eye Surgeon
Gregory Parkhurst, M.D., F.A.C.S., is a board-certified and fellowship trained ophthalmologist, cornea specialist, and refractive eye surgeon. He has tens of thousands of successful eye surgeries, and countless international accolades, to his name — including serving as President of the Refractive Surgery Alliance, a professional society of over 300 refractive eye surgeons from around the world.
He has immense experience with all of the family of vision correction surgeries available today. Celebrities, professional athletes, Olympians, pilots, and countless other eye doctors trust him for their LASIK and PRK. He was among the first in the nation to offer SMILE-LASIK, Visian ICL, and Trifocal intra-ocular lenses for reading vision after 40. And, he’s a dedicated professional who can’t wait to help you achieve clear and comfortable vision correction! As a former laser eye surgery patient himself, he and our team of doctors can relate.
Different Types of IOL
LASIK, or “laser-assisted in situ keratomileusis,” is an all-laser procedure that uses two high-tech lasers to remove the imperfections in your eye causing nearsightedness, farsightedness, and/or astigmatism.
PRK stands for “photorefractive keratectomy,” and is the surgery from which LASIK originated. PRK treats from the surface down, to remove the imperfections in your cornea causing nearsightedness, farsightedness, and astigmatism. This is a great option for patients who aren’t able for LASIK or SMILE due to thin corneas and certain other eye conditions or professional needs.
SMILE® stands for “small incision lenticule extraction.” An extremely precise laser creates small disc of tissue containing the imperfections in your corneal shape, called a “lenticule,” in the lower layers of the cornea. These imperfections are then removed through a micro-opening in top layer of the cornea. This is designed to treat mild to severe myopia, and astigmatism.
Because the ZEISS VisuMax laser’s exacting surgical process has minimal interaction with the cornea’s surface, SMILE is viable even for patients whose cornea issues make LASIK or PRK impossible.
Visian ICL is a proprietary “implantable contact lens” that is unique from LASIK and SMILE, with very similar results. The ICL is a permanent contact lens made of biocompatible collagen that is placed just under the surface of the eye and in front of the eye’s natural lens. Like SMILE, Visian ICL is designed to treat mild, moderate, and even severe nearsightedness, and comes in a toric variety for people with astigmatism. The ICL also blocks UV light, meaning it has built-in sun protection!
RLE (“refractive lens exchange”) can correct for a variety of vision issues by replacing the eye’s aging natural lens with an advanced intraocular lens (IOL) to cover a range of vision from near to far. This is a similar process used in laser cataract surgery, and in RLE, it’s done before cataracts develop! RLE can directly address presbyopia, or nearsightedness caused by an aging eye over 40.
LASIK, or “laser-assisted in situ keratomileusis,” is a procedure where a miniscule flap is created in the cornea — the front of the eye — in order to reshape the tissue underneath it. This helps the eye focus vision better, and can correct for moderate amounts of myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
We’re proud to use the all-laser ALLEGRETTO wavefront-optimized LASIK with IntraLASE® technology to map your unique eye and assist in executing an even safer, faster surgery than traditional LASIK, often with clearer vision correction!
PRK stands for “photorefractive keratectomy,” and is the surgery from which LASIK originated. Rather than creating a flap in the cornea, PRK involves the temporary removal of the top layer of the cornea to operate beneath. This is a great option for patients who aren’t able to get LASIK due to thin corneas and certain other issues.
The ALLEGRETTO wavefront-optimized laser system is equally useful for PRK and LASIK — the primary difference is that only one of its lasers is used during the PRK procedure. It’s just as safe and effective for PRK as for LASIK!
SMILE® stands for “small incision lenticule extraction,” and is a cutting-edge LASIK alternative. An extremely precise laser creates small disc of tissue, called a “lenticule,” in the lower layers of the cornea. This is then removed through a microincision in the side of the cornea. This is designed to treat mild to severe myopia, and some astigmatism.
Because the ZEISS VisuMax® laser’s exacting surgical process has minimal interaction with the cornea’s surface, SMILE® is viable even for patients whose cornea issues make LASIK or PRK impossible. It also reduces the risk of side-effects like dry eye!
RLE (“refractive lens exchange”) can correct for a variety of vision issues by replacing the eye’s aging natural lens, which is removed through a microincision and changed out for an advanced intraocular lens (IOL). This is the same process used in cataract surgery, but in RLE it’s done before cataracts develop! RLE can help directly address presbyopia, or nearsightedness caused by an aging lens.
IOLs can be monofocal, toric for astigmatism, or multifocal. This includes the AcrySof® IQ PanOptix® Trifocal IOL, which is the first and only FDA Approved trifocal IOL, and which offers unparalleled correction across near, mid-distance, and far vision!
