ClinConnect Summary

This clinical trial is looking at the effects of a new 3D visualization system compared to a traditional microscope during a specific eye surgery called ICL (Implantable Collamer Lens) surgery, which is used to treat high myopia or severe nearsightedness. The goal is to see if using 3D technology can improve the health of the retina, the light-sensitive tissue at the back of the eye, after surgery. The study will involve 40 participants aged between 18 and 40 years who have stable high myopia and meet other specific eye health criteria.

If you are eligible to participate, you will undergo either the surgery using the regular microscope or the new 3D system, but all surgeries will be performed by the same experienced surgeon under the same conditions. The study will track your recovery and measure changes in your vision and the health of your retina at various points after the surgery, up to 30 days later. It's important to know that this trial is not yet recruiting participants, but it aims to explore potential advantages of the 3D approach in making the surgery safer and more effective.
