ABSTRACT
AIM:
To evaluate the application effect of iris hooks combined with suture fixation of capsular tension ring(CTR)in the treatment of phacoemulsification with secondary glaucoma associated with lens subluxation.METHODS:
Retrospective case series. A total of 18 eyes of patients with serious secondary glaucoma associated with lens subluxation were enrolled in Aier Eye Hospital(Changchun)from October 2017 to May 2020 as the observation group. All the patients had iris hooks inserted to support the capsule during the phacoemulsification combined with intraocular lens(IOL)implantation. Iris hooks were inserted through the incisions and placed in the capsulorhexis to support the capsule, then CTR was implanted and sutured onto the sclera of the dislocation side. A total of 11 eyes of patients had intracapsular cataract extraction combined with IOL suspension were enrolled in Aier Eye Hospital(Changchun)from October 2015 to October 2017 as the control group. The postoperative complications were recorded. The postoperative examinations included visual acuity, intraocular pressure(IOP)and positions of the capsule and IOL.RESULTS:
The postoperative follow-up at least 12(12-40)mo, both the IOP of observation group and control group returned to normal, with statistically significant difference compared with pre-operation(t=9.994, 8.790, all P<0.001). At 12mo after operation, the best corrected visual acuity of the two groups were significantly improved compared with surgery before(Z=-3.900, P<0.001; Z=-3.002, P=0.003). The IOL in the observation group of the 18 eyes were in the expected position without complications such as an obvious tilt or displacement. In the control group with 11 eyes, the position of IOL in 8 eyes were centered, 3 eyes were slightly biased, and 2 eyes with cystoids macular edema.CONCLUSION:
The application of suture fixation capsular tension ring and iris hooks for secondary glaucoma associated with lens subluxation in patients can be used as an effective auxiliary method, it could effectively control the IOP and maintain long-term stability of the capsule.
