Abstract Details

Purpose:

To evaluate a method for accurately assessing intraocular pressure (IOP) after Fs-LASIK and SMILE surgery.

Setting:

Aier Eye Hospital (Guangzhou)

Methods:

A total of 30 patients (59 eyes) who underwent corneal refractive surgery for myopia were enrolled. Among them, 32 eyes underwent femtosecond-assisted LASIK and 27 underwent SMILE surgery. The IOP was assessed by Corvis, NCT, and Pentacam before and 3 months after surgery, and the consistency of preoperative and postoperative IOP was calculated.

Results:

Corneal morphological changes after corneal refractive surgery affected IOP measurement. The postoperative IOP was lower than the preoperative IOP. The correlation coefficient of IOP before and after surgery was the highest (0.802) and the trend curve was the most regular when IOP was assessed by Corvis. Postoperative IOP decreased by about 1.5 mmHg on average.

Conclusions:

Corvis-measured IOP has the best correlation between preoperative and postoperative measurement after Fs-LASIK and SMILE surgery. It is less affected by corneal morphological changes after corneal refractive surgery. This may be a reliable method to measure postoperative IOP after corneal refractive surgery.
