【摘要】：目的探討放射狀角膜切開術(shù)(RK)術(shù)后白內(nèi)障手術(shù)的診治特點及人工晶狀體度數(shù)選擇的可靠性。方法回顧性分析我院2010年3月~2013年6月RK術(shù)后的白內(nèi)障患者8例(12只眼),術(shù)前對白內(nèi)障患者的視力、角膜曲率及眼軸長度進(jìn)行檢查,比較患者用TOPCON-KR8800型自動角膜曲率計測量的3組角膜中央2.6 mm的角膜曲率值,選擇較為低的K數(shù)值,選用經(jīng)SRK T三元回歸公式自動計算的近正視化(-1.00D~-2.00D)的人工晶狀體(后房型折疊人工晶狀體),行白內(nèi)障超聲乳化摘除聯(lián)合人工晶狀體植入術(shù),術(shù)后3月隨訪患者的視力、屈光狀態(tài)。結(jié)果 RK術(shù)后白內(nèi)障患者行人工晶狀體植入的12只眼術(shù)后視力均較術(shù)前提高:其中6只眼裸眼視力達(dá)到0.8~1.0,另外6只眼裸眼視力達(dá)到0.4~0.6+,矯正視力0.6~1.0;術(shù)后屈光狀態(tài):6只眼接近正視(+0.75D~-1.00D),另外6只眼的屈光度為-1.00D~-2.50D,通過術(shù)后配鏡,患者均能接受。結(jié)論對RK術(shù)后的白內(nèi)障患者,施行白內(nèi)障超聲乳化吸出術(shù)+人工晶狀體植入術(shù)是可行的;比較患者的3組自動角膜曲率計測量的角膜中央2.6 mm的角膜曲率值,選擇較為低的K數(shù)值,使用SRK T公式計算人工晶狀體的度數(shù),預(yù)留-1.00~-2.00D的近視較為安全,避免+3.00D的遠(yuǎn)視出現(xiàn),也較為患者接受。
[Abstract]:Objective to investigate the diagnosis and treatment of cataract after radial keratotomy (RK) and the reliability of intraocular lens selection. Methods from March 2010 to June 2013, 8 patients (12 eyes) with cataract after RK operation in our hospital were retrospectively analyzed. The visual acuity, corneal curvature and axial length were examined before operation. The corneal curvature values of 2.6 mm in the center of the three groups were measured by TOPCON-KR8800 automatic keratometer, and the lower K value was selected. Intraocular lens (IOL) (posterior chamber foldable intraocular lens), which was calculated by SRK T ternary regression formula, was used for cataract phacoemulsification combined with intraocular lens implantation. The visual acuity and refractive state of the patients were followed up 3 months after operation. Results the postoperative visual acuity of 12 eyes with intraocular lens implantation after RK surgery was better than that before operation: the naked visual acuity of 6 eyes reached 0.8 ~ 1.0, and the other 6 eyes achieved 0.4 ~ 0.6 uncorrected visual acuity. The corrected visual acuity was 0.6 ~ 1.0, the refractive state of 6 eyes was close to emmetropia (0.75 DX -1.00 D), and the other 6 eyes was -1.00 DX -2.50 D, which was acceptable to all the patients. Conclusion phacoemulsification and intraocular lens implantation is feasible for patients with cataract after RK. Choosing the lower K value, using SRK T formula to calculate the degree of intraocular lens, it is safe to reserve -1.00D -2.00D myopia, to avoid the appearance of 3.00D hyperopia, but also more acceptable to the patient.
