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.

Cataract Surgery

Light Adjustable Lens Study

This is a randomized, controlled clinical study investigating the safety and effectiveness of the RxSight® Light Adjustable Lens™ in subjects undergoing bilateral cataract surgery and IOL implantation who desire an extended depth of focus.

The Light Adjustable Lens is the first and only FDA-approved IOL that can be adjusted postoperatively to improve uncorrected visual acuity. First, routine cataract surgery is performed, the Light Adjustable Lens is implanted, and then approximately 2-3 weeks after surgery, the Light Delivery Device (LDD) is used to adjust the lens based on the manifest refraction. For this trial, RxSight (the manufacturer of the LAL) has developed a light treatment pattern that is designed to extend depth of focus and improve intermediate and near vision in patients looking to address post-operative presbyopia. We are excited to be part of this clinical trial that may lead to FDA approval for this indication.

Study subjects who meet all inclusion/exclusion criteria will be randomized 1:1 to either undergo bilateral Light Adjustable Lens implantation and light treatments for refractive and presbyopia correction (LAL group) or to undergo bilateral implantation with commercially available IOLs (Tecnis ZCB00 monofocal IOL or Tecnis Toric IOL, Johnson & Johnson Vision) (Control group).

The following is a brief summary of the study inclusion/exclusion criteria:

  • Age 40 to 80
  • BCDVA of 20/40 or worse in both eyes
  • Preoperative keratometric cylinder < 0.75 D in one or both eyes
  • Average dilated pupil diameter of ≥ 7.0 mm in both eyes
  • No significant ocular morbidity (including preexisting macular disease) or previous intraocular surgery in either eye
  • No current use of photosensitizing systemic medications such as doxycycline, chloroquine, amiodarone, and hydrochlorothiazide

If you would like to see whether you are a candidate for this trial, please contact our study coordinator Beverly Socop at 713-626-5544 or There is no fee to participate in the trial, and patients will receive compensation for participating in the study.


This study has completed enrollment.

We have teamed up with RxSight to participate in a clinical trial for a revolutionary cataract lens. We are currently recruiting patients who have had previous refractive surgery (LASIK, LASEK) and are in need of cataract surgery. The revolutionary lens allows us to use a Light Delivery Device (LDD) to adjust any leftover prescription following your cataract surgery.  You will be required to attend timely post-operative visits and may be compensated up to $600.  Please understand this is a 2-step process and you are not guaranteed to qualify until you have met both steps. If you think you may qualify, please call 713-626-5544 to schedule your cataract evaluation.

Laser Vision Correction

RFO Study

This study has completed enrollment.

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:

Hospital/Site: Slade & Baker Vision

PRK Study

UPDATE: We will be introducing some new PRK trials in the near future. If you are interested, please contact us by calling 713-626-5544 or sending us a quick email to:

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!

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.

Allergy Study

UPDATE: We have completed enrollment

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.
