ABSTRACT
@#AIM:To investigate the risk factors of high intraocular pressure after cataract surgery for phacolytic glaucoma(PLG). <p>METHODS: The clinical data of 148 PLG patients(148 eyes)who underwent cataract surgery were analyzed retrospectively. According to the occurrence of postoperative high intraocular pressure, the patients were divided into non-high intraocular pressure group and high intraocular pressure group. Logistic regression analysis was used to evaluate the risk factors of high intraocular pressure after cataract surgery in PLG patients. Nomogram model was constructed, whose predictive ability was evaluated by receiver operating characteristic curve(ROC). <p>RESULTS: There was no significant difference in age, gender, BMI, cataract lens nucleus grade, combined with hypertension, and surgical methods between two groups(<i>P</i>>0.05); the proportion of diabetes, high myopia, preoperative uveitis, preoperative ocular trauma and intraoperative complications in high intraocular pressure group were higher than those of non-high intraocular pressure group, with the difference was statistically significant(<i>P</i><0.05). Logistic regression analysis showed that diabetes, high myopia, preoperative uveitis, preoperative ocular trauma and intraoperative complications were independent influencing factors for high intraocular pressure after cataract surgery in PLG patients. The nomogram model constructed in this study had good fitting effect, and the area under the ROC curve was 0.906(0.890-0.921), indicating that it had strong predictive ability. <p>CONCLUSION: PLG patients with intraoperative complications, preoperative uveitis, ocular trauma, diabetes and high myopia had higher risk of high intraocular pressure after cataract surgery. Clinical doctors should pay more attention to these patients in order to improve the treatment prognosis.
ABSTRACT
AIM: To evaluate the clinical effects of secondary suspensory foldable intraocular lens ( IOL ) implanted in aphakia eyes after vitrectomy.? METHODS: The clinical data were retrospectively analyzed in 25 eyes of 25 patients treated with secondary suspensory intraocular lens implantation after vitrectomy. The surgery was performed through a incision 2. 4mm away from corneal edge, followed by solarometer positioning 8:00 and 2:00, and foldable intraocular lens was loaded and implanted by an injector, after that suspension line knot of lens was made, which length was equal to the distance between the loops of intraocular lens. The intraocular lens was fixed to sclera by a "W"shaped suspension suture. The patients were followed up for 3 ～ 26mo postoperatively, and visual acuity, intraocular pressure, cornea, anterior chamber reaction, intraocular lens position, fundus were observed.? RESULTS: All patients received preoperatively best corrected visual acuity at 1wk after surgery, and the refractive condition was within ± 1. 5 DC. The intraocular pressure was all normal. The number of corneal endothelial cells ( n/mm2 ) was 2394. 33 ± 201. 31 before surgery, and was 2283. 30±217. 82 at 3mo(P>0. 05). The percentage of corneal hexagonal endothelials was 52. 67％±6. 28％ preoperatively, and came to 51. 81％± 6. 41％ at 3mo ( P>0. 05 ). The central corneal thickness (mm) was 541.10±40.31 at the beginning, and was 543.10 ±41. 77 at 3mo (P>0. 05). Small amount of bleeding under choroid occurred in one eye, and intraocular lens dropped into vitreous body in another. Dislocation or shifting of intraocular lens, corneal decompensation or retinal detachment was not observed.? CONCLUSION: The clinical effect of secondary suspensory foldable intraocular lens implanted in aphakia eyes after vitrectomy was satisfactory. Minimal invasive surgery through small incision and accurate implantation are applied to increase safety while reducing complications, thus improve the effects of surgery.
