Application of the capsulorhexis forceps assisted pre-chop performed in cataract surgery / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#AIM:To compare the two techniques of pre-chop and non-pre-chop, and discuss the technical advantages of the capsulorhexis forceps assisted pre-chop.METHODS:Totally 149 cases of age-related cataract were randomly divided into using pre-chop (Group A) and non-pre-chop (Group B) techniques groups, for Group A patients received phacoemulsification after pre-chop by using capsulorhexis forceps.The ultrasonic energy, average phacoemulsification time, intraoperative complications, 1d, 1wk uncorrected visual acuity (UCVA) and 1d, 3d,1wk postoperative corneal edema were recorded and compared.RESULTS:The subgroups of the same group of nuclei were compared in the two groups.The ultrasonic time in Group A was lower than that of Group B, and the difference was significant(P<0.01).Also the corneal edema in the former was lighter than that of the latter(P<0.05).There was difference in uncorrected visual acuity(UCVA) between groups(P<0.05).CONCLUSION:Compared with non-pre-chop, the time of ultrasound in pre-chop group was shorter, the degree of corneal edema was lighter and early postoperative UCVA was better.
