 LASEK, or Laser Assisted Subepithelial Keratectomy, is a modification of the LASIK and PRK procedures. A flap of tissue is created in the outer layer of the cornea with a trephine, which has a finer blade than the microkeratome used in LASIK. The eye is bathed in a special solution. Then the flap is lifted so the central cornea may be treated with an excimer laser. More of the cornea is exposed for treatment than with LASIK, making LASEK a better choice for patients who require greater vision correction. After treatment the flap is replaced and allowed to heal. A contact lens may be worn for a few days until recovery is complete. Advantages of LASEK over PRK are diminished pain, shorter recovery time and a lower risk of infection.
The IntraLase® FS laser is a highly precise tool aiding in corneal flap creation, the first step in laser vision correction surgery. During the procedure, the IntraLase laser fires 15,000 pulses per second into the cornea, where the flap can be created at a depth and diameter determined by the surgeon as appropriate for each individual patient. In addition to benefiting from this pinpoint (2-3 micron) accuracy, patients who undergo surgery conducted with the IntraLase laser are less likely to need an enhancement (follow-up) procedure than with other technologies.
 A cataract is a cloudy area in the normally clear lens in the front of the eye. Cataracts are caused by a chemical change of unknown origin in the eye, and cause blurred or distorted vision. They cannot be prevented from forming, but early detection through regular eye exams can help maintain the clearest vision possible.
People at risk for developing cataracts are over 55 years old, have had eye injuries or disease, have a family history of cataracts, smoke cigarettes or use certain medications. There is no pain associated with the condition, but there are several symptoms that indicate failing vision due to cataracts. These include:
- Blurred/hazy vision
- Spots in front of the eye(s)
- Sensitivity to glare
- A feeling of "film" over the eye(s)
- A temporary improvement in near vision
Vision loss from cataracts can often be corrected with prescription glasses and contact lenses. For people who are significantly affected by cataracts, replacement surgery may be the preferred method of treatment. During cataract replacement, the most common surgical procedure in the country, the lens is removed and replaced with an artificial one called an intraocular lens or IOL.
Our practice now uses AcrySof ® ReSTOR® IOLs in cataract surgery. These state-of-the-art lenses are uniquely designed to improve vision at all distances - up close, far away and everything in-between - giving cataract patients their best chance ever to live free of glasses. The AcrySof® ReSTOR® IOL was designed to provide quality near to distance vision by combining the strengths of apodized diffractive and refractive technologies.

The Visian ICL is an implantable contact lens that works with the eye to correct vision. Unlike traditional contact lenses that go on the surface of the eye, Visian ICL is surgically inserted into the eye where it provides excellent quality of vision for a wide range of correction needs.
Established technology, worldwide acceptance
The Visian ICL is the first lens of its kind to receive FDA approval for use in the US. It is based on many years of research and development in adapting the proven technology of the IOL (Intraocular lens) used for cataract surgery. The IOL cataract procedure is familiar to ophthalmologists and is performed safely on millions of patients each year. While the technology is similar, the Visian ICL procedure differs from cataract surgery, as the natural lens is not removed from the eye. Instead, Visian ICL is placed in front of the natural lens and works with it to correct vision.
Dr. Hatsis implants first Phakic Implant 1996 as part of FDA Investigations
As a clinical investigator Dr. Hatsis implanted the first lenses of this type back in 1996 as part of the FDA clinical trials. The lens that was used was the predecessor of the Visian ICL. Dr. Hatsis has 10 year follow up experience on these patients.
Procedure done in Rockville Centre office
Dr. Hatsis has a State Approved Operating Suite in the Rockville Centre office. These procedures will be preformed there one eye at a time with approximately 5 days in between each. The procedure is done under topical anesthesia and generally takes 10 minutes.
