METHODS: A retrospective study was used. From August 2013 to February 2016, 160 LASEK patients(160 eyes)in our hospital were selected. Visual acuity after operation was recorded. The incidence and influence factors of high intraocular pressure were investigated. The treatment method and prognosis of high intraocular pressure were recorded.

RESULTS: In the 160 patients, all patients had complete epithelial flap and different degree of photophobia. There were 19 patients with postoperative photophobia, conjunctival hyperemia and foreign body sensation significantly. At postoperative 3mo, average intraocular pressure were 18.40±4.98mmHg, which was higher than that of preoperative, 16.27±2.24mmHg(P<0.05), and at postoperative 3mo, visual acuity was significantly higher than preoperative(P<0.05). There were 9 patients with postoperative steroid induced ocular hypertension, the incidence rate was 5.6%; Multiple linear regression analysis showed that the cutting depth(OR=3.209), maximum diameter of curvature(OR=3.071)and fundus C/D(OR=9.224)value were the main risk factors leading to postoperative steroid induced ocular hypertension(P<0.05).

CONCLUSION: The postoperative steroid induced ocular hypertension in LASEK is common, but has no obvious effect on visual acuity. The cutting depth, maximum diameter, curvature fundus C/D value were the main influencing factors, so we should careful use the hormone drugs in treatment and prevention. Periodic review and detection for change of intraocular pressure are needed.
