Overview
This trial hypothesized that novel laser refractive surgery techniques (LASIK, KLEx) or laser-assisted cataract surgery (FLACAS) could suppress postoperative inflammation and improve recovery in patients by reducing oxidative stress generated by the surgical procedure. It is also intended to verify whether the new laser technology is necessary for clinical use in groups with low antioxidant activity through the detection of antioxidant activity in the eyes of patients.
Description
Simultaneously measure total reactive oxygen species (ROS), antioxidant capacity (TAC) and ascorbic acid (AA) in aqueous humor (cataract surgery only) or tears. All patients underwent the same examination at our institution, including uncorrected visual acuity (UCVA), intraocular pressure (IOP), as well as central corneal thickness (CCT) with pneumatic tonometer, apparent refraction with autorefractor, and corneal curvature with keratometer. The axial length (AXL), anterior chamber depth (ACD) and lens thickness (LT) were measured by optical biometer.
Eligibility
Inclusion Criteria:
- at least 20 years old
- corneal refractive surgery or cataract surgery patients
Exclusion Criteria:
- patients with eye infections
- presence of severe retinal disease
- presence of severe eye injury or severe ptosis
