Abstract：Objective: To study the influence of small scleral tunnel incision and clear corneal incision phacoemulsification (PHACO) on ocular surface function indexes and anterior chamber depth in patients with cataract. Methods: One hundred and fifty patients with cataract (monocular disease) who were scheduled to undergo PHACO treatment in the hospital from August 2022 to January 2024 were selected and divided into scleral group (small scleral tunnel incision PHACO, n=75) and corneal group (clear corneal incision PHACO, n=75) by adopting simple random grouping method (random number table method). The ocular surface function indexes, anterior chamber depth, corneal endothelial cell (CEC) loss rate, dry eye symptoms and postoperative complications were compared between groups. Results: The tear break-up time (BUT) in the two groups was decreased first and then increased, and the BUT in the scleral group at T1, T2 and T3 was longer than that in the corneal group (P<0.05). The corneal surface asymmetry index (SAI) and corneal surface astigmatism (CYL) were enhanced first and then reduced in both groups, and the SAI and CYL were lower in the scleral group than those in the corneal group at T1, T2 and T3 (P<0.05). The peripheral and central anterior chamber depth of the two groups showed an increasing trend, but the change trend of the two groups was the same, and the difference was not statistically significant (F interaction =2.384, 2.376, P>0.05).The scleral group had lower CEC loss rate at T1, T2 and T3 than the corneal group (P<0.05). The score of ocular surface Disease Index Scale (OSDI) of the two groups increased first and then decreased, but the change trend of the two groups was the same, and the difference was not statistically significant (F interaction =1.930, P>0.05). There was no statistical significance in postoperative complications between the scleral group (18.67%) and the corneal group (29.33%) (P>0.05). Conclusion: Compared with PHACO with clear corneal incision, PHACO with small scleral tunnel incision for cataract patients can promote the recovery of corneal surface morphology and reduce the loss of corneal endothelial cells, with good treatment safety.
