Clinical Trials

Slade & Baker Vision Center is constantly being sought out by device and pharmaceutical companies to conduct clinical trials in order to help them gain FDA approval. Often, patients who are eligible for these clinical trials receive significant discounts for their participation. Current clinical trials being conducted at Slade & Baker Vision Center are listed below. Please call our office to learn more.

Allergy Study

Itchy eyes and runny nose from seasonal allergies? Do you have allergies in the fall?

Join our upcoming study at Slade & Baker Vision Center in Houston. We are currently enrolling participants to evaluate a new investigational eye drop for treating the signs and symptoms of eye allergies!

Starting soon, Slade & Baker Vision Center in Houston is conducting an allergy study to evaluate how effective a new eye drop is at treating the signs and symptoms of ragweed allergies. If you experience allergy symptoms in the fall and are at least 18 years old, you may qualify to participate. The study involves 5 office visits over the course of approximately 5 to 8 weeks and you may be compensated up to $350 for your time.  Participants will need an allergy skin test prior to enrollment in the study and allergy skin tests will be provided at no cost.

For more information and to find out if you may qualify, contact 713-626-5544!


RFO Study

Slade & Baker Vision is currently conducting a medical research study for people who have at least one eye that has impaired vision, who don’t see well, or may not be able to see at all even with glasses or contacts.  The purpose of this study is to collect data on the basic safety and function of an investigational laser when used on people’s eyes.  Participation would involve laser surgery on your eye with limited vision and at least 7 visits to our clinic.

You may qualify to participate in this research study IF:

  1. You are at least 22 years of age or older
  2. You have limited vision in at least one of your eyes
  3. Your eye with limited vision:
    • Has not had previous surgery on the front of the eye (the cornea)
    • Has not had cataract surgery
If you are interested in participating, please contact:

Visumax SMILE

UPDATE: We have completed enrollment!

Carl Zeiss Meditec and Slade & Baker Vision Center were conducting a research study on a new laser procedure, SMILE, designed to correct nearsightedness and astigmatism.

SMILE is an alternative to LASIK and designed to accomplish the same visual result as the LASIK procedure. It was finally FDA approved!

If you:

  1. You have nearsightedness with astigmatism
  2. You are at least 22 years of age
  3. You have had no previous eye surgery, significant trauma or infections in either of your eyes.
  4. You have a pair of glasses that are at least 1 year old
  5. You are in good general health
  6. You are willing to take your contact lenses out several weeks before surgery.

If you are all of the above and want to see if you are a candidate for SMILE, please call 713-626-5544.

Corneal Crosslinking (CXL)


UPDATE:  As of April 2016, Corneal Crosslinking CXL is now APPROVED in the US by the FDA!  Slade & Baker Vision Center was the first site in Texas to perform corneal cross linking as part of a clinical trial. We are excited to announce that this trial has ended and CXL is now a regularly approved procedure in the US.  We offer screening evaluations, at no charge, for patients with corneal ectasia and/or KERATOCONUS to find out their options.

CXL is designed to treat Keratoconus, a disease that results in increasing nearsightedness and astigmatism. CXL may also be used to treat certain complications after refractive surgery (i.e. LASIK or PRK), primarily Post Lasik Ectasia patients that experience corneal thinning after Refractive Surgery. CXL treatment consists of a combination of applying Riboflavin drops, a B vitamin, to the front surface of the eye along with the use of an ultraviolet light. CXL has been approved in other parts of the world for multiple years and has now finally been approved in the US this year (2016). Dr. Slade was a lead investigator for the FDA Study that gained approval for this procedure. While any procedure, even wearing contact lenses, carries some risks, CXL is associated with low risks. In the other parts of the world, where CXL has been approved for years, results have been excellent.

The best first step is to come in to the clinic for a screening evaluation to find out if you are eligible. Please visit our corneal crosslinking page to learn more. We look forward to seeing you!

Raindrop® – Near Vision Corneal Inlay for Presbyopia


The Raindrop Clinical Study was being conducted at several specialized ophthalmology centers throughout the U.S. Slade & Baker Vision Center was the only site in Houston, TX where the clinical trial had been offered and as of August 30th 2016, Dr. Slade was the first surgeon in the US to perform the procedure outside of the clinical trials which was live streamed!  This was previously referred to as the “Presbylens” study.

Our research coordinator, Chadisty Pauly was recently honored by Revision Optics as the Research Coordinator of the year for the Raindrop study we participated in.

Fueled by a belief that no one should ever have to hold a menu out at arm’s length, RVO developed the Raindrop® Near Vision Corneal Inlay, a unique patented refractive surgery solution. This inlay is designed to improve the near vision that has been lost by the eye’s natural aging process, presbyopia. The Company is actively pursuing regulatory approvals for Raindrop® worldwide, and is committed to ridding the world of reading glasses, one satisfied patient at a time which is why Slade & Baker Vision Center has joined forces and offered this procedure to their patients.

Presbyopia is the loss of near vision with age and it typically happens to everyone over 40 years of age. The Raindrop procedure consists of the creation of a small LASIK-like flap made with a laser; the inlay is laid on the cornea under the flap; and the corneal flap is returned to its original position where it bonds without stitches. No corneal tissue is removed and the lens is removable if needed. This technique has been approved in Europe and we assisted in finally gaining its approval this month (July 2016) in the US! If you or a loved one has developed presbyopia, please visit our Raindrop Corneal Inlay page for more information on this procedure or call us at 713-626-5544 to set up an appointment.

T-CAT Study


This LASIK study was for patients who are nearsighted, farsighted or have astigmatism. In this study we used a new, custom LASIK treatment pattern. The treatment pattern had been approved in Europe and we were assisting in gaining its approval in the US. Early results were impressive. A significant reduction in the cost for LASIK was provided to patients for their participation. Qualifying patients were 18 years of age or older.
