Effect of anterior vitrectomy combined with intraocular lens suspension on intraocular pressure and corneal endothelium in treatment of lens dislocation
[Objective]To investigate the effects of anterior vitrectomy combined with intraocular lens suspension on intraocular pressure and corneal endothelium in the treatment of lens dislocation.[Methods]Totally 92 cases of lens dislocation diagnosed and treated in Luohe Third People's Hospital(Luohe Maternal and Child Health Hospital)from January 2019 to December 2022 were retrospectively analyzed and treated with anterior vitrectomy combined with intraocular lens suspension.The optimal corrected visual acuity,intraocular pressure,corneal endothelial count and postoperative complications were compared before and after surgery.[Results]The intraocular pressure of 92 patients decreased after operation,a statistically significant difference was observed(P＜0.05).Postoperative corneal endothelial count of 92 patients had no significant change compared with that before surgery,with no statistical significance(P＞0.05).Postoperative visual acuity of 92 patients improved to varying degrees,of which 67 patients had corrected visual acuity ≥0.3,and the difference was statistically significant compared with that before surgery(P＜0.05).Postoperative uveitis reaction occurred in 8 eyes of 92 patients,early mild cornea in 6 eyes,vitreous hematoma in 1 eye,and intraocular hypertension in 1 eye,all of which returned to normal after conservative treatment.[Conclusion]Anterior vitrectomy combined with intraocular lens suspension treatment can effectively control the intraocular pressure of patients with lens dislocation,causing less damage to the corneal endothelium,creating favorable conditions for intraocular lens suspension,thereby effectively improving the vision of patients and speed up the recovery of patients.Although there will be few postoperative complications,they all return to normal after appropriate conservative treatment,which does not affect the study results.
