LASIK Studies



Discover Vision regularly participates in clinical research for LASIK laser vision correction, presbyopia-correcting intraocular lens (IOL) implants, cataracts, glaucoma and more. To see if you are eligible, please call 816.350.6903 for more information, or use the QUICK CONTACT form on this page.

Current Studies include: MEL90 LASIK Study & RxSight Light Adjustable Lens (LAL) for Cataracts


Carl Zeiss Meditec MEL90 LASIK Study

The purpose of this research study is to evaluate the safety and effectiveness of the Carl Zeiss Meditec MEL-90 excimer laser system used to perform LASIK for nearsightedness, farsightedness, astigmatism and mixed astigmatism.

Eligible patients will have one eye or both eyes treated with LASIK using the MEL-90 excimer laser system.  All participants will be followed for one year after the procedure.  Participation in this study is voluntary.  If you choose to participate, you will be given a thorough examination at each visit.  Surgery will be provided at no cost; however, you must agree to participate in follow up appointments for 1 year.

We are nearing the end of this portion of the LASIK study.  Qualifications include:

  • Hyperopia up to +5.00D with astigmatism up to -4.00D
  • Mixed Astigmatism with Hyperopia up to +3.75D and Astigmatism up to -4.00D
  • No previous eye surgery of any kind
  • No visually significant cataracts

The primary aim of the MEL90 LASIK Study research is to evaluate the safety and effectiveness of LASIK using the MEL-90 excimer laser system in patients with nearsightedness farsightedness, astigmatism and mixed astigmatism.  If you would like to be considered for this study, please fill out the form below or contact our research study coordinator at 816.350.6903.


RxSight Light Adjustable Lens (LAL)

Do you have cataracts? If so, you may be eligible to participate in a research study for the Light Adjustable Lens (LAL) which allows an eye doctor to adjust the power of the lens after it has been implanted in your eye.

The purpose of this clinical study is to evaluate the safety and effectiveness of the Light Adjustable Lens in improving intermediate and near uncorrected vision while maintaining distance vision. The study will compare the results obtained with the Light Adjustable Lens to the results obtained with patients implanted with another commercially available intraocular lens (IOL).

Approximately 230 men and women will participate in this study. During this study, patients will have a 50% (1/2) chance of receiving Light Adjustable Lenses and a 50% (1/2) chance of receiving Bausch + Lomb IOLs. The cataract surgery in each eye will occur on 2 different days at least 7 days apart, and patients will need to return to the study doctor’s office for evaluation over a 6-month to 1-year period.

Six different centers within the United States will participate in this study which will analyze how well RxSight’s Light Adjustable Lens improves vision after the natural cataract lens has been removed and replaced.

Discover Vision Centers is one of only six practices in the country participating in the research. We still have a few openings in the study. Our team would be happy to help determine if you meet the criteria.  Contact our research study coordinator at 816.350.6903.

  • Between 40 and 80 years old, in overall good health.
