AIM:To observe the effect of phacoemulsification on the ocular surface in patients with conjunctivochalasis and cataract.

METHODS:Totally, 150 cases(200 eyes)of cataract patients accepted phacoemulsification and intraocular lens implantation form September 2014 to December 2014 in our hospital were retrospectively analyzed. All the cases were divided into two groups, normal group(110 cases with 140 eyes)and conjunctivochalasis group(40 cases with 60 eyes)according to coexisted with conjunctivochalasis or not. Follow up lasted 3～6mo. The breakup time(BUT)of tear film, foreign body sensation, epiphora and conjunctival congestion of two groups were observed before and after operation and statistically analyzed. The time, these factors took to recover to preoperative state were observed too.

RESULTS:The differences of the BUT of two groups before and after the operation was statistically significant(t=20.93, 19.16; both P=0.00). The differences of the two groups after operations in terms of ocular foreign body sensation, epiphora and conjunctival congestion had statistical significance(P=0.00). The time these observed factors of two groups took to recover to preoperative state was significantly different(t=17.16, 14.18, 27.41; all P=0.00).

CONCLUSION:The ocular surface conditions are significantly worse after phacoemulsification and intraocular lens implantation in cataract patients. Conjunctivochalasis could significantly delay the recovery of ocular surface function after cataract surgery.
