NCT07512089 · Status: NOT_YET_RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 100

No results posted yet for this study

Summary

The goal of this clinical trial is to learn if laser blended vision (LBV) works better than traditional monovision LASIK to correct presbyopia in adults aged 40 to 55 years. Presbyopia is an age-related condition that makes it hard to see things up close. The study will also evaluate the safety of both procedures.

The main questions it aims to answer are:

Does LBV improve distance, intermediate, and near vision at the same time after surgery? Is LBV as safe as traditional monovision LASIK?

Researchers will compare laser blended vision to traditional monovision LASIK to see if LBV provides better overall vision after surgery.

Participants will:

Be randomly assigned to receive either laser blended vision or traditional monovision LASIK Have standard eye examinations before surgery Undergo LASIK surgery using the assigned method Return for follow-up visits at 1 week, 1 month, 3 months, and 6 months after surgery Complete vision tests and questionnaires about visual quality and satisfaction

Conditions

Interventions

PROCEDURE

Laser Blended Vision LASIK

Laser blended vision LASIK is a refractive surgery technique for presbyopia correction. The dominant eye is corrected for distance vision, and the non-dominant eye is adjusted to mild myopia to improve near vision using a laser blended vision design.

PROCEDURE

Traditional Monovision LASIK

Monovision LASIK is a refractive surgery technique in which the dominant eye is corrected for distance vision and the non-dominant eye is corrected for near vision to improve presbyopia.
