摘要
本文总结了20例22眼白内障术后无晶体眼配框架镜与角膜接触镜的矫正视力比较.角膜接触镜矫正视力等于或优于框架镜的占86%,为求较好矫正视力,在应用换算公式计算屈光度后大部分病例需再主觉验光,酌性调整屈光度,使其获双眼单视.物像放大降低至5～9%,无环形暗点,视野扩大,无球面差或错位感.
A comparison of corrected visual acuity between spectacles and contact lens on 20 cases of aphakia after cataract extraction was presented. The number that corrected visual acuity of contact lens wearers is the same or better as the spectacles make up eighty percent. In order to get a good corrected visual acuity, we calculated patients' needed diopters according to formula and performed optometryfor them mostly. The results show that the contact lens wearers have the function of bi-fixation and they have no annular scotomata, spherical deviation or illusion of position sense. The objective magnification of contact lens wearers decrease to 5-9%.
