LASIK, SMILE, and PRK for Vision Correction
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial examines how three types of eye surgeries—LASIK, SMILE, and PRK—affect vision and quality of life for physicians. The goal is to determine how these treatments might reduce the need for glasses. It suits physicians or medical students who haven't undergone eye surgery and seek more freedom from glasses. Participants must speak English, be 21 or older, and attend follow-up appointments for a year. As an unphased trial, this study allows participants to contribute to valuable research that could improve vision correction options for medical professionals.
Do I need to stop my current medications for this trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial team or your doctor.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that LASIK, PRK, and SMILE surgeries are generally safe, though each has potential side effects.
For LASIK, studies indicate that 99.5% of patients achieve 20/40 vision or better. However, some may temporarily experience dry eyes, glare, halos, or trouble seeing at night after the procedure.
PRK is also considered safe, with complications being rare and usually minor. Patients might feel as if something is in their eye or experience blurry vision and tearing, which typically resolve quickly. Long-term risks include changes in vision and dry eyes.
SMILE surgery is known for its high safety and stable results. However, some may see glare or halos around lights at night. Large studies report low rates of serious complications.
In summary, while these eye surgeries are generally well-tolerated, they can have temporary side effects. Most patients recover well and achieve improved vision.12345Why are researchers excited about this trial?
Researchers are excited about LASIK, SMILE, and PRK surgeries because they offer distinct approaches to correcting vision in physicians. LASIK is unique with its use of a laser to create a flap in the cornea, allowing for a quick recovery time and minimal discomfort. SMILE stands out by using a minimally invasive technique that doesn't require a flap, potentially reducing the risk of dry eye. PRK, on the other hand, removes the cornea's outer layer entirely and allows for a more gradual healing process, which can be beneficial for patients with thinner corneas. Each of these methods provides unique advantages, making them promising options for those in the medical field seeking vision correction.
What evidence suggests that this trial's treatments could be effective?
Research has shown that LASIK surgery is highly effective, with 99% of patients achieving 20/20 vision or better. Most patients express satisfaction, with 98% happy with their results. In PRK surgery, over 90% of patients also achieve 20/20 vision or better, and 95% are pleased with the outcome. For SMILE surgery, studies indicate that 90% of eyes reach 20/20 vision three years after the procedure. This trial will compare LASIK, PRK, and SMILE, all of which have demonstrated excellent results in improving vision and patient satisfaction in previous studies.16789
