Purpose: To observe the changes in corneal Q value preoperatively and postoperatively in cataract patients and to further explore the influence of incision positions on Q value.
Setting: The Peking University Third Hospital, Beijing, China.
Design: Retrospective nonrandomized study.
Methods: Eyes that implanted intraocular lens (IOL) ZCB00 or Zeiss 839 were included. The corneal Q values were compared preoperatively, 1 week and 1 month postoperatively, the incision positions were divided into groups to review the influence on Q values.
Results: We finally analyzed 158 eyes of 103 patients, the corneal Q values decreased significantly postoperatively, and the Q values tend to be stable at 1 month after surgery. Moreover, the Q values in superior incision group and temporal incision group were lower than that in nasal, nasal and temporal arc group at both 1 week and 1 month after surgery with statically significance; the reduction of angle kappa postoperatively had obvious advantages in the superior and temporal incision group.
Conclusions: Corneal Q-value would change after cataract surgery, and the influence of incision position on corneal Q-value need still to be further clear, clarifying the influence of surgical operation, especially incision making, on corneal Q-value will achieve better vision and visual quality after cataract surgery.
