Abstract:
AIM: To investigate the effect of corneal topography-guided phacoemulsification with transparent corneal incision on cataract patients.METHODS:A total of 92 cataract patients(92 eyes)admitted to our hospital from February 2021 to February 2023 were prospectively selected and randomly divided into two groups: the control group(46 eyes)received the conventional 11:00 clear corneal incision scheme, and the study group(46 eyes)received the steepest meridian clear corneal incision scheme. The uncorrected visual acuity, corneal surface morphology indicators, including surface regularity index(SRI), surface asymmetry index(SAI), and cylinder(CYL), subjective dry eye symptoms questionnaire scoring scale(SDES), tear film break-up time(BUT), and complications were compared between the two groups.RESULTS:All patients completed the follow-up. The uncorrected visual acuity of the study group was significantly better than that of the control group at 1 wk, 1 and 3 mo after surgery(all P<0.05); there were statistical significance in the SAI and CYL of both groups of patients at 3 mo after surgery(all P<0.05); the fluctuation levels of SDES and BUT in the study group were significantly lower than those in the control group at different time points after surgery(all P<0.05); and there was no statistical difference in complications between the two groups(P>0.05).CONCLUSION:Under the guidance of corneal topography, phacoemulsification through the transparent corneal incision of the steepest meridian of the cornea can improve the uncorrected visual acuity of cataract patients, restore the corneal surface morphology, and have few complications.
