백내장 수술 후 절개 방법에 따른 안압 변화 비교 (Comparison of Intraocular Pressure after Cataract Surgery According to Incisional Techniques)

목적: 백내장 수술 후 안압 변화를 절개방법에 따라 차이가 있는지 알아보고자 하였다.
대상과 방법: 초음파유화술 후 수정체낭내 인공수정체 삽입술을 시행한 환자를 두 군으로 나누어 술 전, 술 후 1주, 1개월, 3개월, 6개월,12개월, 18개월, 24개월째 측정한 안압을 비교 분석하였다.
결과: 전체 77명(100안)의 환자를 투명각막절개군(28명 33안)과 공막터널절개군(49명 67안)으로 나누었고 술 전 두 군의 평균 안압은유의한 차이가 없었다(p=0.908, student t-test). 술 후 1주 투명각막절개군은 평균 2.22 ± 2.57 mmHg (p＜0.001, Repeated-measures ANOVA with post hoc analysis), 공막터널절개군은 평균 2.11 ± 2.50 mmHg (p＜0.001, Repeated-measures ANOVA with post hoc analysis)의 유의한 안압 하강 효과를 보였고 술 후 24개월까지 유의하게 낮은 채로 유지되었다. 술 후 24개월까지 두 군 간의절개 방법에 따른 안압 변화의 유의한 차이는 없었다(p=0.848, repeated measures ANOVA).
결론: 초음파유화술을 이용한 백내장 수술 시 장기간 안압 하강의 효과가 있으며 절개법에 따른 술 후 안압 하강 효과의 차이는 없을것으로 생각한다.

Purpose: In the present study we compared the intraocular pressure (IOP) after cataract surgery according to incisional techniques.
Methods: Patients who underwent phacoemulsification with intraocular lens implantation were divided into 2 groups: clear corneal incision group (CC group), and scleral tunnel incision group (ST group). All complicated cases were excluded. IOP was measured preoperatively and at 1 week, 1, 3, 6, 12, 18 and 24 months after surgery.
Results: Seventy-seven patients (100 eyes) were enrolled in the present study; CC group (28 patients, 33 eyes), ST group (49 patients 67 eyes). Preoperative IOPs in both groups were not significantly different (p = 0.908, student’s t-test). IOP in the CC group at 1 week after surgery significantly decreased 2.22 ± 2.57 mm Hg compared to preoperative IOP (p < 0.001,repeated-measures ANOVA with post hoc analysis), and the IOP of the ST group decreased 2.11 ± 2.50 mm Hg (p <0.001, repeated-measures ANOVA with post hoc analysis). The lowered IOP was maintained for 24 months postoperatively.
There was no significant difference in IOP change after surgery depending on incisional techniques (p = 0.848, repeated measures ANOVA).
Conclusions: There may be no difference in IOP lowering effect after surgery depending on incisional techniques.
