ABSTRACT
AIM: To compare one step macular hole and cataract surgery with two step surgery in patients with macular hole and cataract. ●METHODS: ln a clinical trial conducted on patients suffering from cataract with macular holes inTabriz, the effects of simultaneous surgery of macular hole and cataract performed on these patients were studied. ln this study, 22 patients ( Group A ) were, first, undergone phacoemulsification and intraocular lens embedment, and one month later, 23-gauge pars plana vitrectomy together with the retinal internal limiting membrane ( lLM ) removal. Twenty - one patients ( Group B ) were undergone simultaneous phacoemulsification, intraocular lens embedment, 23-gauge pars plana vitrectomy, and the retinal lLM removal. ●RESULTS: Group A was comprised of 7 males and 15 females, and Group B of 9 males and 12 females ( P=0. 545) . The mean age of patients in Group A and B were 66.63±4. 75 and 67. 71±4. 99y, respectively (P=0. 472). Three months after surgeries were performed, the macular holes of 2 patients from Group A and 5 patients from Group B were open ( P = 0. 240 ). Uveitis was observed in 1 patient from Group A and 4 from Group B (P=0. 185). The increase of intraocular pressure (lOP) was merely observed in 2 patients from Group B ( P=0. 233 ) . Posterior capsule opacification ( PCO ) was observed, three months after surgeries, in 2 patients from Group A and 4 from Group B (P=0. 412). ● CONCLUSION: The results suggested that, no significant difference existed between patients from the two groups in terms of outcome and postoperative complications, although,Group B patients, the recipients of simultaneous surgeries, experienced more complications compared to their Group A counterparts.
ABSTRACT
To investigate the characteristics of scale cataract operations and the effects and experiences of small incision extracapsular cataract extraction with intraocular lens ( lOL) implantation in large - scale vision recovery action. ●METHODS: Four thousand eight hundred ninety - two cases ( 4892 eyes ) of cataract were treated by small incision non-phacoemulcification cataract extraction from March 2010 to November 2011 in our hospital ( Fuming No. 1 surgery car of Shaanxi Province ) which were retrospectively analyzed. Visual acuity, intraoperative and postoperative complications, the recovery of postoperative inflammation were observed. ●RESULTS: Visual acuity reached 0. 3 or more in 4521 eyes (92. 42%) at 1d after the operation, at 3d after the operation in 4571 eyes (93. 44%), there were 4887 eyes with lOL implantation, implantation rate was 99. 90%. All the cases had lesser intraoperative and postoperative complications, and the postoperative inflammation recovered quickly. ●CONCLUSlON: Small incision extracapsular cataract extraction with lOL implantation is simple, effective, economical, safe and adapting for large - scale vision recovery action.
ABSTRACT
AIM: To compare the visual acuity and contrast sensitivity of eyes with different corneal spherical aberration implanted with the same aspherical IOL and evaluate the effect of different ocular spherical aberration on visual performance after phacoemulsification. METHODS:It was a prospective case series study. Forty-six eyes of thirty-nine age-related cataract patients in our department were included. The patients were divided into 3 groups according to the value of preoperative corneal spherical aberration. Eyes with corneal spherical aberration≤0. 2μm were assigned to group A, those with corneal spherical aberration >0. 2μm and ≤0. 3μm to group B, and those with corneal spherical aberration≥ 0. 3μm to group C. All patients underwent phacoemulcification and recieved AcrySof IQ aspheric IOL. Uncorrected visual acuity ( UCVA ) , best-corrected visual acuity( BCVA) , contrast sensitivity, and total ocular higher - order aberrations for a 6. 0mm pupil were recorded 3mo postoperatively. ANOVA were used to analyze the data. RESULTS: There were no significant differences in UCVA and BCVA between the 3 groups (P=0. 287, 0. 115). Contrast sensitivity was no statistically significant difference between the 3 groups at any spatial frequency under photopic、 mesopic, and mesopic with glare conditions (P>0. 05). With a 6. 0mm pupil diameter, root mean square values for total ocular higher - order aberrations were lower in groups A and B than that in group C (P=0. 000). The difference of total ocular spherical aberration was statistically significant between the 3 groups (P=0. 000). Coma and trefoil were similar between the groups (P=0. 788,0. 590), with no statistically significant differences.CONCLUSION:Implantation of the same aspherical IOL in eyes with different corneal spherical aberration results in similar visual acuity and contrast sensitivity. Small differences of ocular spherical aberration after phacoemulsification have no effect on visual performance.
