Clinical effect comparison of phacoemulsification and small incision cataract extraction and their effects on ocular surface

Objective To observe the clinical effect of small incision cataract extraction and phacoemulsification and their effects on ocular surface.Methods A total of 44 cataract patients(44 eyes) from 2009 to 2010 in our hospital were chosen,according to the surgical type,the patients were randomly divided into observation group and control group,22 cases in each group,the small incision cataract extraction and phacoemulsification were performed,respectively.The preoperative and postoperative visual acuity,postoperative complications were observed,and the corneal sensitivity and tear secretion at postoperative 1 day,1 week,1 month were examined.Results The postoperative visual acuity in observation group was from 0.05 to 0.29 in 4 eyes,from 0.30 to 0.49 in 6 eyes,from 0.50 to 0.79 in 8 eyes,from 0.80 to 1.00 in 4 eyes,which in control group was 6 eyes,10 eyes,4 eyes,2 eyes;Compared with control group,the visual acuity of observation group was better,there was statistical difference(P0.05).Compared with control group,the prevalence of each complication in observation group was obviously decreased,there was statistical difference(P0.05).At postoperative 1 day,1 week,1 month,the central,superior and inferior corneal sensitivity of observation group was significant better than that of control group,there were statistical differences(all P0.05);There was no statistical difference in tear secretion between two groups(P0.05).Conclusion Compared with phacoemulsification,the small incision cataract extraction is simple and convenient with rapid postoperative recovery.
