目的 观察硬性透气性角膜接触镜(rigid gas permeable contact lens,RGPCL)对圆锥角膜患者的屈光矫正作用.方法 临床病例系列研究.收集2010年1月至2012年12月在天津市眼科医院就诊的圆锥角膜患者40例(72只眼),根据最大拟似角膜计值(SimKmax)将患者分为两组:SimKmax≤47 D为轻度组,共24例(43只眼);SimKmax＞47 D为中重度组,共16例(29只眼).分别观察两组患者配戴RGPCL前后的最佳矫正视力、角膜地形图变化和眼部病变进展情况.结果 在40例(72只眼)中,38例(70只眼)圆锥角膜患者完成12个月随访,并通过配戴RGPCL后均获得较好的矫正视力(0.6～1.0),角膜病变进展得到一定缓解,未发现有眼部明显并发症.另2例(2只眼)中,有1例轻度组患者(1只眼)因配戴后无法适应而放弃使用;余1例中重度组患者(1只眼)因病情加重和矫正视力下降,在戴镜3个月后行穿透性角膜移植手术.结论 科学合理地长期配戴RGPCL,可使圆锥角膜患者获得较好地矫正视力,延缓病情进展或推迟角膜手术时间.
目的 觀察硬性透氣性角膜接觸鏡(rigid gas permeable contact lens,RGPCL)對圓錐角膜患者的屈光矯正作用.方法 臨床病例繫列研究.收集2010年1月至2012年12月在天津市眼科醫院就診的圓錐角膜患者40例(72隻眼),根據最大擬似角膜計值(SimKmax)將患者分為兩組:SimKmax≤47 D為輕度組,共24例(43隻眼);SimKmax＞47 D為中重度組,共16例(29隻眼).分彆觀察兩組患者配戴RGPCL前後的最佳矯正視力、角膜地形圖變化和眼部病變進展情況.結果 在40例(72隻眼)中,38例(70隻眼)圓錐角膜患者完成12箇月隨訪,併通過配戴RGPCL後均穫得較好的矯正視力(0.6～1.0),角膜病變進展得到一定緩解,未髮現有眼部明顯併髮癥.另2例(2隻眼)中,有1例輕度組患者(1隻眼)因配戴後無法適應而放棄使用;餘1例中重度組患者(1隻眼)因病情加重和矯正視力下降,在戴鏡3箇月後行穿透性角膜移植手術.結論 科學閤理地長期配戴RGPCL,可使圓錐角膜患者穫得較好地矯正視力,延緩病情進展或推遲角膜手術時間.

Objective To evaluate the treatment efficacy of rigid gas permeable contact lens (RGPCL) for correcting the irregular astigmatism patients with keratoconus.Methods From January 2010 to December 2012,a retrospective analysis of 72 eyes from 40 patients with keratoconus were collected in our hospital.According to the Sim Kmax value,the keratoconus were divided into two groups:the mild keratoconus group and the moderate to severe keratoconus group.Sim Kmax ≤ 47D was the mild keratoconus group (24 patients,43 eyes),and Sim Kmax ＞47D was the moderate to severe keratoconus group (16 patients,29 eyes).The best corrected visual acuity,the findings with slit-lamp microscopes and the change of ocular health were observed at beginning,six and twelve months after the fitting with RGPCL.Results Among the 40 patients (72 eyes),there were 38 patients (70 eyes) completed the 12 months' follow up.The good corrected visual acuity was observed in all of the patients who completed the 12 months' follow up after fitting with RGPCL.The progression of corneal ectasia was prevented and the ocular complications with RGPCL were not found.Among another two patients (2 eyes),One patient (one eye) in mild group was given up because of intolerance with the fitting.Another one patient (one eye) in the moderate to severe group was received the penetrating keratoplasty because of the progression of the corneal ectasia and decreased of visual acuity.Conclusions The exciting fitting with RGPCL for the patients with severe keratoconus with a longtime could significantly improve the corrected visual acuity,and prevent the progression of corneal ectasia or delay the time of the keratoplasty operation.
