At Hines Sight in Denver, Colorado, we perform laser eye surgery procedures ranging beyond Denver laser vision correction to treat the many variations of refractive error. Our other refractive procedures include PRK, denver cataract surgery, refractive lens exchange, the new Epi-LASIK, and phakic intraocular lens implants. Whether you suffer from myopia (nearsighted), hyperopia (farsighted), astigmatism, presbyopia (need reading glasses or bifocals when wearing best distance vision correction) or cataracts, we can help you see the world clearly again.


PRKHines Sight is proud to be one of the first centers in Colorado to offer the latest in LASIK vision correction, Epi-LASIK. This exciting new procedure combines features of PRK and LASIK for truly advanced laser eye surgery.

In traditional PRK and LASEK vision correction, alcohol is used to remove or separate the surface epithelium, a unique new machine separates the epithelium (surface skin) from the cornea completely and cleanly with little delay in the process. Therefore, the time from starting the procedure to beginning the laser portion is considerably less, leaving less time for drying of the cornea and eliminating this source of inaccuracy.

There is also a much lower risk of surgical flap complications than with LASIK vision correction and other laser eye surgery procedures. Epi-LASIK also reduces the possibility of post-operative Dry Eye Syndrome. This procedure is frequently recommended for patients with extremely sensitive eyes. By effecting 35 percent less corneal tissue than traditional LASIK, Epi-LASIK allows many people with thin corneal tissue to receive laser vision correction.

PRK (Photorefractive Keratectomy)

Our Denver, Colorado center offers Photorefractive Keratectomy, often called PRK. PRK is a laser eye surgery suited for patients with refractive error who are not good candidates for LASIK vision correction. PRK uses the same type of excimer laser to reshape the cornea so that light may properly focus on the retina, and you can see clearly.

PRK differs from LASIK vision correction in that it does not involve the creation of a flap to reshape the cornea. The advantage of PRK is that patients who are not candidates for LASIK may still regain better vision through refractive laser eye surgery. However, PRK does require a longer recovery process, and vision is not restored as quickly as LASIK vision correction. Also, a temporary, protective contact lens is worn after PRK to reduce postoperative discomfort and promote healing.

PRK patients are incredibly pleased with the results of their PRK treatment at Hines Sight, and enjoy clear vision every day. Dr. Coco will work with you to decide which laser vision correction is best for you. Contact our Denver, Colorado office today to discuss your options!

For those patients that don't qualify for LASIK or other Laser refractive procedures due to having a highly nearsighted or farsighted prescription, and/or corneas that are too thin or misshapen, we offer the option of the Visian ICL and the Verisyse Phakic Intraocular Lens or Clear Lens Extraction with intraocular lens implantation.

Visian Phakic ICL
A.K.A. The Implantable Contact Lens

The clear choice for superior visual quality.

The Visian ICL is a new refractive surgery technology (like LASIK, or Epi-LASIK) that is the best for correcting higher amounts of myopia (near-sightedness), eyes with thin corneas for whom LASIK isn't recommended, or those with dry eyes which may be made much worse by LASIK. The Visian ICL is a phakic intraocular lens ("phakic" means that the natural crystalline lens is left in the eye). Visian ICL is a good alternative for LASIK. The doctors at Hines Sight were among the first to perform the Visian ICL eye surgery and have extensive experience with the procedure.

The Visian ICL offers superb quality of vision while maintaining excellent contrast sensitivity. Unlike other refractive surgeries, the Visian ICL is reversible. The Visian Implantable Contact Lens is FDA approved and over 75,000 have been implanted to date. Visian ICL surgery does not permanently alter the shape or structure of the front of the eye and is inserted through a very small (2.8 millimeter), self-sealing (no stitches required) incision allowing good vision shortly after surgery and is very quick healing. All other FDA approved phakic intraocular lenses require 6-millimeter incisions, which heal much slower and often cause considerable astigmatism.

Implanting the Visian Phakic ICL is an outpatient procedure that takes around 30 minutes. One eye is treated at a time; however, this procedure can be performed on the same day for both eyes. Anesthetic drops will be placed in the eye. For better access to your eye, the doctor will use an instrument to comfortably hold your eyelids open during the procedure. The surgery is done under local anesthesia so the procedure is virtually painless. Next, a small incision is made in the cornea and the Visian ICL is placed behind the pupil, in front of the lens and works with the natural lens to correct vision. The Visian ICL is invisible in the eye. A shield will then be placed over your eye to protect it until you are seen the following morning for the first postoperative exam.

The Visian ICL provides ultraviolet (UV) light protection helping to guard against the development of macular degeneration and cataracts. The Visian ICL is made from Collamer, the most biocompatible intraocular lens material.

The Visian ICL is another option for treating near-sightedness and provides unparalleled clarity of vision. Studies have shown it to be the clear choice for superior vision quality.

Verisyse Phakic IOL

The Verisyse Phakic intraocular lens ("Phakic" means that the natural crystalline lens is left in the eye) is designed for those who may not be a candidate for laser vision correction due to very high myopia or very thin corneas, and in the future high farsightedness. Its advantage is that the natural lens remains in place to focus from far to near in a natural way. It is intended for younger patients who can still focus well. The Verisyse Phakic IOL is still appropriate for older patients, greater than 45 years old, who can still focus but to a reduced degree.

The procedure involves placing a properly selected intraocular lens implant behind the cornea and in front of the iris to greatly diminish dependency on glasses or contact lenses, often eliminating them. Often patients who have astigmatism may require further laser vision correction to "tweak" their vision.

Implanting the Verisyse Phakic IOL is an outpatient procedure that takes around 30 minutes. Usually, one eye is treated at a time. To begin the surgery drops will be placed in the eye in order to reduce the pupil size. For better access to your eye Dr. Coco will use an instrument to comfortably hold your eyelids open during the procedure. The surgery is done under local anesthesia so the procedure is virtually painless. Next, a small incision is made in the cornea for the Verisyse lens to be placed in the space between the iris and the cornea. The lens is then gently attached to the iris (the colored part of the eye) to hold the lens in place. The small incision is then closed with microscopic stitches that dissolve on their own. A shield will then be placed over your eye to protect it until you are seen the following morning for the first postoperative exam.

Even though this Phakic IOL has been recently approved for use, it has been safely used in over 150,000 patients and is the safest of all intraocular lens implants used. Although the Verisyse Phakic IOL is intended to be permanent, the procedure is reversible if desired or necessary.

Clear Lens Extraction with intraocular lens implantation (Refractive Lens Exchange)

When one is not a good candidate for the usual laser vision corrective procedures, then most often an intraocular lens implant can be placed inside the eye to correct the vision. One type of this method is the Refractive lens exchange. In this case, the natural lens inside the eye is removed and replaced with an artificial implant, called an intraocular lens, in order to correct your farsightedness or nearsightedness. The power of this intraocular lens is calculated by a computer using a complex equation. There are occasions where LASIK and/or PRK are needed after the Clear Lens Extraction in order to fine-tune the vision, eg. when there is astigmatism.

The main difference between standard cataract surgery and clear lens extraction is that cataract surgery is primarily performed to remove a patient's cataract that is obscuring and clouding their vision, while refractive clear lens extraction is performed to reduce a person's dependence on glasses or contact lenses. Clear lens extraction can be combined with Laser Vision Correction to treat astigmatism. People who have clear lens extraction now, will not have to have cataract surgery in the future.

The clear lens extraction procedure is performed on an outpatient basis. Only one eye will be treated at a time. After the eye is completely numbed with topical or local anesthesia, the eye's natural lens will be gently vacuumed out through a tiny incision, about one-eighth of an inch wide.

Next, the new intraocular lens will be folded and inserted through the same micro-incision. It will then be unfolded and placed into the "capsular bag" that originally surrounded the natural lens. The incision is "self-sealing" and usually requires no stitches. It remains tightly closed by the natural outward pressure within the eye. This type of incision heals fast and provides a much more comfortable recuperation.
