RESUMO
AIM:To investigate how to design personalized cataract surgery programs to achieve surgical correction of preoperative corneal astigmatism with surgical astigmatism under the guidance of corneal topography, improve postoperative visual quality and reduce the cost of treatment. METHODS: Totally 202 cases ( 226 eyes ) cataract patients were divided into randomized treatment group and individualized treatment group. According to the method and location of the incision, randomized treatment group were divided into 8 groups. Surgical astigmatism after different incision were calculated with the use of preoperative and postoperative corneal astigmatism through vector analysis method. Individualized treatment groups were designed personably for surgical method with reference of every surgically induced astigmatism, the surgical method chooses the type of surgical incision based on close link between preoperative corneal astigmatism and surgically induced astigmatism, and the incision was located in the steep meridian. The postoperative corneal astigmatism of individualized treatment group was observed. RESULTS: Postoperative corneal astigmatism of individualized treatment group were lower than that of 3.0mm clear corneal tunnel incision in the randomized treatment group, there were statistically significance difference, while with 3. 0mm sclera tunnel incision group there were no statistically significance difference. After 55. 8% of patients with the use of individualized surgical plan could undergo the operation of extracapsular cataract extraction with relatively low cost and rigid intraocular lens implantation, the per capita cost of treatment could be reduced. CONCLUSION: Personalized cataract surgery programs are designed to achieve surgical correction of preoperative corneal astigmatism under the use of corneal topography, improve postoperative visual quality and reduce the cost of treatment.
RESUMO
AIM: To discuss the complications and prevention of phacoemulification in primary angle-closure glaucoma after trabeculectomy. METHODS:Retrospective analysis of 33 cases (37 eyes) phacoemulification in primary angle-closure glaucoma after trabeculectomy in our hospital between January 2008 and June 2012, followed up 12-33mo, intraoperative and postoperative complications were observed. RESULTS: Compared with pre-operation, intraocular pressure hadn't increased in follow-up 6mo. Iris was injured in 5 eyes, corneal edema was in 14 eyes, anterior chamber inflammation was in 16 eyes, all symptoms were improved in 3-7d. And no case with posterior capsule rupture or vitreous loss. CONCLUSION: Phacoemulification is an effective way for the treatment of cataract after angle-closure glaucoma trabeculectomy, careful preoperative examination, intraoperative prevention can reduce or avoid the occurrence of surgical complications.
