AIM:

To investigate the corneal biomechanical parameters alteration after phacoemulsitication with 2.4mm corneal incision within 1mo by Corvist ST.<p>

METHODS:

A self control study was performed. Twenty-eight age related cataract patients(56 eyes), who were in accordance with the inclusion criteria, received phacoemulsification with 2.4mm corneal incision from March to September in 2019. Corneal biomechanical parameters were measured preoperatively and postoperatively on 3d, 6d and 30d by Corvis ST.<p>

RESULTS:

The first applanation length(A1L), the second applanation time(A2T)and corneal thickness(CCT)were significantly different between preoperation and postoperation(<i>F</i>=10.534, 11.655, 14.734; all <i>P</i><0.05). The value of A1L on 3d postoperative was significantly increased than that on the day before operation, 6d and 30d postoperative, while the A2T value was significantly reduced(<i>P</i><0.05). But there was no different in A2L and A2T between preoperation and 6d postoperative(<i>P</i>>0.05). The value of central corneal thickness(CCT)was significantly increased on 3d and 6d postoperative compared with the preoperative parameter(<i>P</i><0.05). The value of CCT got the maximum value on the 3d after surgery, and recovered to the preoperative level on the 30d after surgery. <p>

CONCLUSION:

Phacoemulsitication with 2.4mm corneal incision change the corneal biomechanical preoperties. The corneal biomechanical parameters are basically recovered in the 30d postoperative.
