The effect of phacoemulsification under transparent corneal incision and scleral tunnel incision on the treatment of age-related cataract and its impact on vision
Objective To explore the effect of phacoemulsification under transparent corneal incision and scleral tunnel incision on the treatment of age-related cataract and its impact on vision.Methods 88 patients(single eye)with age-related cataract were selected as the study subjects.They were divided into group A and group B using a number table method,with 44 cases in each group.Group A received phacoemulsification under transparent corneal incision cataract,while group B received phacoemulsification under scleral tunnel incision.Comparison was made on tear film break-up time(BUT),basal tear production,subjective dry eye score(SDES),corneal fluorescein sodium staining score,visual quality and vision recovery,and the incidence of postoperative complications between the two groups.Results At 2 weeks after surgery,BUT in both groups was shorter than that before surgery in this group,the basal tear production was less than that before surgery in this group,and SDES score and corneal fluorescein sodium staining score were higher than those before surgery in this group;BUT of(7.15±1.74)s in group B was longer than(3.25±1.85)s in group A;the basal tear production of(11.23±3.05)mm/5 min in group B was more than(7.15±2.84)mm/5 min in group A;group B had subjective dry eye score(SDES)of(1.39±0.58)points and corneal fluorescein sodium staining score of(4.15±1.63)points,which were lower than(1.89±0.62)and(6.25±1.32)points in group A(P<0.05).At 2 weeks after surgery,the visual quality score in both groups was lower than that before surgery in this group,and the naked eye vision,corneal astigmatism,and best-corrected vision were higher than those before surgery in this group;group B had visual quality score of(20.15±3.23)points and corneal astigmatism of(1.03±0.61)°,which were lower than(31.41±3.84)points and(1.28±0.52)° in group A;group B had naked eye vision of(0.82±0.21)and the best corrected vision of(0.46±0.09),which were higher than(0.63±0.17)and(0.35±0.08)in group A(P<0.05).There was no significant difference in the incidence of postoperative complications between group A and group B(P>0.05).Conclusion Phacoemulsification under scleral tunnel incision is more conducive to vision recovery in the treatment of age-related cataracts.It can not only reduce dry eye syndrome and foreign body sensation,but also reduce corneal astigmatism without increasing postoperative complications,and has promotional value.
