| Objective:By performing cataract phacoemulsification combined with multifocal intraocular lens AMO Tecnis ZMB00 and monofocal intraocular lens AMO Tecnis ZA9003 implantation in cataract patients with different axial lengths.The quality of visual functions and related quality of life in such patients preoperatively and postoperatively were compared and analyzed.Methods:A pospective non-randomized controlled study.A total of 71 cataract patients(88 eyes)were selected.Axial length(AL)is divided into 4 groups:22 mm≤AL≤24 mm group,24 mm<AL<26 mm group,26 mm<AL≤28 mm group,AL>28 mm group.The eyes in each group are then divided into 2 groups:monofocal intraocular lens group(implanted intraocular lens AMO Tecnis ZA9003)and multifocal intraocular lens group(implantation of intraocular lens AMO Tecnis ZMB00).All selected cases were measured preoperatively,one week after operation,one month after operation and three months after operation.Compare uncorrected distance visual acuity(UDVA),corrected distance visual acuity(CDVA),uncorrected near visual acuity(UNVA),higher order aberration,average height of modulation transfer function(MTF AH)and Strehl ratio(SR).At three months after operation,patients in each group underwent VF-14 Chinese revised visual quality of life questionnaire.SPSS22.0 software was used to process the data,p<0.05 was statistically significant.Results:1.There was no statistically significant difference between the UDVA,CDVA and UNVA preoperatively in both groups 1 and 2(p>0.05).The UDVA and CDVA of patients in groups 1and 2 postoperatively were improved compared with those preoperatively.UDVA,CDVA and UNVA stabilized at 1 week after operation.Among them,there was no statistically significant difference between the UDVA and CDVA in the A1 and A2 groups after operation(p>0.05).After surgery,the U-NVA of the A2 group was significantly better than that of the A1 group(p<0.05).There was no statistically significant difference in the CDVA between the B1 and B2 groups postoperatively(p>0.05).After operation,UDVA and UNVA of group B2 were significantly better than those of group B1(both p<0.05).There was no statistically significant difference in CDVA and UNVA between the C1 and C2 groups after operation(both p>0.05).After operation,the UDVA of group C2 were significantly better than those of group C1(p<0.05).There was no statistically significant difference in CDVA and UNVA between the D1 and D2 groups after operation(p>0.05).After operation,the UNVA of group D2 were significantly better than those of group D1(p<0.05).2.Under the 3mm pupil,the trefoil,coma,and spherical aberration of the patients in groups 1 and 2 were lower than those preoperatively.There was no statistically significant difference in coma,spherical aberration and trefoil among patients in A1 and A2 group,B1 and B2 group,C1 and C2 group,D1 and D2 group preoperatively(p>0.05).There was no difference in coma,spherical aberration,and trefoil among patients in the A1 and A2 groups,B1 and B2 groups,C1 and C2 groups,D1 and D2 groups after operation.(p>0.05).3.Under the 3mm pupil and correcting all low order aberrations,the average height of MTF of patients in groups 1 and 2 is higher than that preoperatively.There was no statistically significant difference in the average,height of MTF between the A1 and A2 groups,B1 and B2 groups,C1 and C2 groups,D1 and D2 groups preoperatively(p>0.05).There was no statistically significant difference in the average height of MTF between the A1 and A2 groups,B1 and B2 groups,C1 and C2 groups,D1 and D2 groups after surgery(p>0.05).4.Under the 3mm pupil and correcting all low order aberrations,the SR of patients in groups 1 and 2 is higher than that preoperatively..There was no statistically significant difference in SR between A1 and A2 groups,B1 and B2 groups,C1 and C2 groups,D1 and D2 groups preoperatively(all p>0.05).There was no statistically significant difference in the SR between the A1 and A2 groups,B1 and B2 groups,C1 and C2 groups,D1 and D2 groups after surgery(p>0.05).5.After operation,VF-14 Chinese revised visual quality of life questionnaire showed that the difference in visual function between group 1 and group 2 was statistically significant(p<0.05),differences in self-care,activities,social and psychological aspects was no statistical significance(all p>0.05).Conclusions:1.For the cataract patients with different axial lengths,multifocal intraocular lens and monofocal intraocular lens can improve patients’ vision after cataract operation,but multifocal intraocular lens can provide better near visual acuity.After cataract operation,the objective visual quality of multifocal intraocular lens and monofocal intraocular lens is basically the same with high order aberrations,average height of MTF and SR under normal daytime conditions.But the Multifocal intraocular lens subjective visual quality of life score is better than monofocal intraocular lens.2.Patients with long axial lengths can obtain similar visual quality as implanted monofocal intraocular lens after implantation of multifocal intraocular lens.Patients with high myopia and long axial lengths have good adaptability to multifocal intraocular lens.Multifocal intraocular lens can be applied to patients with long axial lengths. |
