Interested in participating in
a research study?
The eye doctors and staff of Durrie Vision are continuously involved with research studies for advanced vision correction procedures. In some cases, the clinical study procedures are performed at a discounted rate for the patient.
Current studies
Femtosecond Laser Study -- Blade-free LASIK
Blade-free LASIK provides an all laser approach to laser vision correction. The femtosecond laser is a computer-controlled alternative to a mechanical microkeratome for creating corneal flaps in the LASIK procedure. To make the corneal flap, the laser beam is focused into a tiny spot of energy that passes harmlessly through the outer layers of the cornea creating microscopic bubbles at a specific depth within the central layer of the cornea. There the bubbles disintegrate and the corneal flap procedure is created, silently and painlessly, with remarkable precision.
Durrie Vision is currently involved in a research study comparing 2 different femtosecond lasers used to create the corneal flap. To qualify for this research study, you must qualify and undergo the LASIK procedure (at a reduced cost) and meet other criteria that will be evaluated by the study doctor.
Corneal Sensitivity Study
Efforts to promote the re-connecting of the corneal nerves are being evaluated to assist with "speeding up" the healing process following LASIK. The ability of topical cyclosporine (Restasis) to promote this reconnection has been evaluated in a recent study and showed a greater corneal sensitivity in those eyes that received the cyclosporine.
Durrie Vision is currently involved in a clinical research study to evaluate the ability of Restasis to accelerate the recovery of corneal sensitivity following LASIK.
To qualify for this study, you must qualify for and and undergo the LASIK procedure (at a reduced cost) and meet other criteria that will be evaluated by the study doctor.
Refractive lens exchange (RLE) uses the successful techniques of modern cataract surgery. The natural lens of the eye is removed and and replaced it with a silicone or plastic intraocular lens (IOL). This procedure has been successful at correcting most, if not all, nearsightedness and farsighteness.
IOL companies have responded to today’s active aging population by developing lenses that offer a full range of function. These new lenses offer improved vision for people with presbyopia -- better reading vision is now a possibility.
Durrie Vision is currently involved in a research study to compare different types of intraocular lenses used in performing RLE. To qualify for this research study, you must undergo RLE (at a reduced cost) in both eyes and meet other criteria that will be evaluated by the study doctor.
Phakic Intraocular Lens Study
Durrie Vision is conducting a clinical trial using a new intraocular lens implant. The intraocular lens is a foldable version of a lens that is commercially available for use in the US. Both lenses are designed to be implanted between the cornea (transparent front part of the eye) and the iris (colored part of the eye).
Potential study participants need to be at least 21 years of age with an eyeglass prescription from -5.0 D to -14.5 D. You may be a candidate for this study if you are not eligible for LASIK or any other corneal procedures.
Study participants will be followed for approximately three years and will be compensated for time and participation in the study. They will receive the lens implant surgery for both eyes at a discounted rate of more than 50%.
As with any surgical procedure, you should ask your physician about potential risks, side effects, or complications.
Acufocus ACI 7000 Inlay
A healthy, young eye is able to focus light from both far and near objects to create a clear image at all distances. However, by age 45 virtually everyone experiences softening of focus at near points such as reading or working at the computer. This is a natural occurrence that affects us the rest of our life, even if we still have good distance vision. This condition is called presbyopia.
The “Presbyopic” eye of a 45 year old is unable to focus light from a near object, creating a blurred image when performing near tasks like reading or dialing a cell phone.

The AcuFocus ACI™ 7000 blocks out unfocused light and only allows focused light to hit the retina. This makes close objects clear.

Recently a clinical study has been initiated to prove the safety and effectiveness of the Acufocus ACI™ 7000, a micro-thin inlay designed to improve near vision, and eliminate the inconvenience of reading glasses.
To qualify for this study, you must be between the ages of 45 and 60 and meet other medical criteria that will be evaluated by your doctor.
Take the first step towards reducing your dependence on reading glasses! Ask Durrie Vision if the ACI™ 7000 clinical trial is right for you.
A Clinical study of the Acrysof Angle-Supported Phakic IOL for the Treatment of High Myopia
Durrie Vision is participating is a research study using a new investigational intraocular lens for the correction of near-sightedness (glasses prescription between -6.00 and -16.50 Diopters). You may be eligible for this study if you are not eligible for LASIK or other corneal surface procedures. This investigational lens is currently being evaluated in Europe, Canada and the United States. Durrie Vision is one of the United States clinical centers that will participating in this research study.
High myopia (the type of myopia required for enrollment into Alcon’s Phakic IOL study) occurs when the anatomy of an eye causes light rays to be focused in front of the retina.
Convergence of light at a focal point in front of the retina yields blurry vision. The nearsighted condition is graphically represented below.
Alcon’s Phakic IOL is a small flexible lens designed to be implanted between the cornea (transparent front part of the eye) and the iris (colored part of the eye).
In a technique similar to cataract lens surgery, the physician folds the IOL and inserts it into the anterior chamber (space between the cornea and the iris) through a small incision in the cornea. The lens then gently unfolds and is positioned in the anterior chamber.
Once in place, the lens redirects light rays focusing them closer to the retina. This redirection of light is intended to correct for myopia.
At this time, an investigational study has been approved to assess implantation of this lens at selected sites. You must be able to tolerate a contact lens in the non-study eye for at least 90 days (about 3 months).
Study participation requires a minimum of 13 visits over a 3 year period.
As with any surgical procedure, you should ask your doctor about the potential risks, side effects, and complications.
Dry Eye Study -- Natural Tears Comparison
Dry eye is a result of inadequate wetting and lubrication of the eye. Millions of people experience dry eye symptoms. It can often be mistaken for infections or allergies.
There are many factors that can contribute to the development of dry eye, such as environment, aging, hormonal changes, autoimmune diseases, medications, and eye surgery.
Many patients suffer mild to severe ocular dryness for several months following surgery. Approximately 95% of patients experience dry eye symptoms on the first day post-LASIK and 59% of these patients still experience dry eye symptoms one month after surgery.
Durrie Vision is currently involved in a clinical research study to compare 2 different tear formulas, to document the effectiveness of the tears in controlling dry eye following refractive surgery.
To qualify for this study, you must qualify for and undergo the LASIK procedure (at a reduced cost) and meet other criteria that will be evaluated by the study doctor.
The quality of vision depends on the way the eye captures the image and the way the brain processes that image.
Visual Training Program
NeuroVision’s Neural Vision Correction™ (NVC) technology has been developed through research focused on optimizing performance of how the brain processes vision. During this “visual training” program, a patient is exposed to a set of visual perception tasks on a computer screen. The patient then indicates if the target is seen, by use of the computer mouse. Based on the patient’s responses, the treatment plan is formulated within the system. This patient specific program is designed to train the functions in the brain that were ineffective. During each session, the patient’s responses are analyzed and adjust the level of visual difficulty to the range most effective for visual improvement. This training consists of 20-30 consecutive treatment sessions administerd 2-3 times per week.
Durrie Vision is currently testing the effectiveness of NVC in improving the vision of subjects with low degrees of myopia, early presbyopia, early changes in the vision due to Macular Degeneration and cataracts, and improving visual outcome after undergoing LASIK.
