Recruiting studies
- NCT07146828Recruiting
High-precision vision test for laser eye surgery
This trial tests a very precise way to measure vision (0.05 diopter steps) for people getting SMILE laser eye surgery. The goal is to see if this fine-tuning leads to better results.
Nantong, JiangsuAges 18–40 - NCT06625749Recruiting
AccuraSee lens implant to improve near vision after cataract surgery
This trial tests an artificial lens (AccuraSee IOPCL) placed inside your eye to help you see better up close and at intermediate distances after having cataract surgery. It is for people who still need reading glasses and have a specific type of monofocal lens already in their eye.
Cleveland, OhioAges 22 years+ - NCT06982807Recruiting
SMILE laser for stable nearsightedness
This study tests a new laser correction method called SMILE 4.0-VISULYZE to treat nearsightedness and other refractive errors. It may help people who are tired of glasses or contact lenses and want a quick, low-pain vision fix.
Nantong, JiangsuAges 18–40 - NCT07481487Recruiting
Cataract and vision correction surgery outcomes
This trial looks at results after cataract or vision correction surgery, like lasik or lens implants. It helps doctors improve care.
Bristol, EnglandAges 18 years+ - NCT07096232Enrolling by invitation
AI vs doctor for eye surgery and keratoconus diagnosis
This study compares an AI system to a specialist eye doctor to see which is better at diagnosing vision problems like nearsightedness, farsightedness, astigmatism, and keratoconus. Your existing medical records will be used to see how well the AI performs.
Cairo, MaadiAges Any age - NCT07050498Recruiting
Can virtual reality reduce anxiety before eye surgery?
This study tests if watching a virtual reality experience can help lower anxiety in adults about to have refractive (vision-correcting) surgery. If you're feeling nervous before your procedure, this simple, drug-free approach might help you relax.
MarseilleAges 18 years+ - NCT05670626Enrolling by invitation
ICL eye lens fit based on eye measurements
This study looks at how your current eyesight prescription relates to specific front-eye measurements to help choose the right implant (ICL) and its space (vault). It may help patients who have high myopia or astigmatism and can’t safely have LASIK.
Cairo, Cairo GovernorateAges 21–45 - NCT06924944Recruiting
A study of a new lens for people who had laser eye surgery
This study looks at how well a type of artificial lens (Clareon Vivity) works for people who have had laser eye surgery in the past and now need cataract surgery. It aims to see if this lens gives good vision without glasses.
Ogden, UtahAges Any age - NCT05856786Recruiting
Study how eye focusing surgery changes OCT measurements
This study looks at how refractive (vision-focusing) surgery affects OCT test images inside the eye. It may help doctors measure and track eye changes more accurately after surgery.
Omaha, NebraskaAges 19 years+ - NCT06658119Recruiting
Wide-focus lens for cataract surgery: a clinical trial
This study tests a new type of lens implant that gives you a wider range of clear vision after cataract surgery. It uses a special laser to help remove the cataract, and the lens may help you see better at near, far, and in between without glasses.
Hangzhou, ZhejiangAges 40–80 - NCT05037370Recruiting
Compare two eye laser procedures for vision correction
This study compares two types of laser surgery for vision problems (PRK versus another approach called “WFO ablation”) to see which works better for clear sight. You may be a candidate if you meet specific eye measurements and can return for follow-up visits.
San Antonio, TexasAges 21–50 - NCT06448468Recruiting
Eye microbes in dry eye after LASIK
This study looks at the bacteria and other microbes on the eye's surface in people who develop dry eye after LASIK surgery. It aims to understand how these microbes change and may help improve future treatments for dry eye after LASIK.
Nanchang, JiangxiAges 18–45 - NCT06555289Recruiting
New lens implant after prior laser vision correction
This study tests a new type of artificial lens (Clareon PanOptix Pro) for people who have had LASIK or PRK in the past and now need cataract surgery. It aims to see how well the lens works for these patients, potentially improving vision after surgery.
Albuquerque, New MexicoAges 45 years+ - NCT07201298Recruiting
Comparing laser eye surgery methods for nearsightedness
This study compares a new type of laser surgery (ray-tracing guided) to three other standard laser methods for correcting nearsightedness with or without astigmatism. It aims to see which approach provides the best vision correction.
Draper, UtahAges 22–50 - NCT00532051Recruiting
Test eye scans to choose the right cataract lens power
This study is looking at how special eye scans (optical coherence tomography, or OCT) can help doctors calculate the correct power of a cataract lens after you’ve had laser vision correction before. It may help improve how well your new lens matches your eye after prior laser treatment.
Portland, OregonAges 18 years+ - NCT07512115Recruiting
Eye Surgery Alignment Study for Nearsightedness
This study tests whether a small adjustment during laser eye surgery for nearsightedness improves your vision outcomes. You'll be randomly assigned to receive either standard surgery or surgery with a minor compensation adjustment, and researchers will compare how well you see afterward.
Guangzhou, GuangdongAges 18–40 - NCT07070037Recruiting
Long-term vision after congenital cataract surgery
This study looks at how good a child's vision and eye prescription are 5 years after surgery for a cataract they were born with. The goal is to understand long-term results and help guide care for future patients.
Shanghai, Shanghai MunicipalityAges Up to 18 years - NCT04693663Enrolling by invitation
Relex-SMILE treatment for leftover nearsightedness after cataract surgery
This trial tests whether Relex-SMILE eye laser surgery can improve nearsightedness that remains after you’ve already had cataract surgery. It’s meant for people with a certain range of leftover nearsightedness, while excluding certain eye problems and prior eye procedures.

Common questions
- Are there clinical trials for refractive surgery?
- Yes. Clin2 currently lists 18 recruiting refractive surgery studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a refractive surgery trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a refractive surgery trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
