为评价孔源性视网膜脱离（ＲＲＤ）成功地环扎加压手术后视力、眼屈光状态、前房深度、晶体厚度和眼轴长度的改变，用ＴｏｐｃｏｎＲＭ－Ａ２３００屈光计测量眼屈折力，Ｔｏｐｃｏｎ－ＯＭ－４角膜曲率计测量角膜屈折力，前房深度、晶体厚度和眼轴长度用ＤＧＨ／Ｊｅｄｍｅｎ４０００型Ａ超定。随访６个月，５２例（５２眼）ＲＲＤ依环扎程度分为Ａ组２８眼（＜２２．３７％）和Ｂ组２４眼（＞２２．３７％）。结果在手术后近视有明显增加，散光度Ａ组增加，Ｂ组不增加，散光轴位无改变，角膜屈折力增加不明显，眼轴长度增加，前房深度减少，而晶体厚度无明显改变。结论认为在成功地对ＲＲＤ施行环扎加压手术后，眼轴长度延长与近视程度增加明显相关（Ａ组ｒ＝２．８３７，Ｐ＜０．０５；Ｂ组ｒ＝１３．９２９，Ｐ＜０．０１），术后视力也有明显增进（Ｐ＜０．０１）。
To evaluate the eye refractive power, ocular refractive status, anterior chamber depth, crystal thickness, and ocular axial length change after rhegmatogenous retinal detachment (RRD) was successfully performed with a TopconRM-A2300 refractometer, Topcon-OM-4 keratometer measured corneal refractive power, anterior chamber depth, crystal thickness and axial length DGH / Jedmen4000 A overdetermined. During follow-up of 6 months, 52 eyes (52 eyes) were divided into 28 eyes (22.37%) in group A and 24 eyes (22.37%) in group B according to the degree of cerclage. Results There was a significant increase of myopia after surgery. A group of astigmatism increased, group B did not increase, axis of astigmatism was unchanged, corneal refractive power increased insignificantly, axial length increased, anterior chamber depth decreased, while crystal thickness had no significant change. Conclusions: After the successful operation of cerclage and compression surgery on RRD, the prolongation of axial length was significantly associated with the increase of myopia (r = 2.837, P <0.05 in group A, r = 13.929 in group B, P < 0.01), postoperative visual acuity also significantly improved (P <0.01).
