Seventy-six corneal transplants performed by one surgeon for pseudophakic bullous keratopathy (PBK) were studied. The mean follow-up was 23 months (range 2-76). Of 41 eyes with lenses left in situ, the mean acuity was 20/45; 60.9% of the eyes saw 20/40 or better. In contrast, the mean acuity for 18 eyes with lens removal and 17 eyes with intraocular lens exchange was 20/52 and 20/62, respectively; 42.8% saw 20/40 or better. Eighty-three percent of all grafts remained clear. Vitreous loss, glaucoma, and cystoid macular edema were more common with eyes with lens removals and exchanges. The type of lens present at transplant for PBK did not affect visual outcome. Although the results were not statistically significant, this study suggests that lenses left in situ are associated with a better visual prognosis, and that there is no difference in the clinical results between aphakic and pseudophakic bullous keratopathy.
对一位外科医生进行的76例因假晶状体大泡性角膜病变（PBK）而实施的角膜移植手术进行了研究。平均随访时间为23个月（范围2 - 76个月）。在41只保留原位晶状体的眼中，平均视力为20/45；60.9%的眼睛视力达到20/40或更好。相比之下，18只摘除晶状体的眼睛和17只进行人工晶状体置换的眼睛的平均视力分别为20/52和20/62；42.8%的眼睛视力达到20/40或更好。所有移植片中83%保持透明。玻璃体脱出、青光眼和黄斑囊样水肿在摘除晶状体和进行晶状体置换的眼中更为常见。PBK移植时存在的晶状体类型不影响视觉结果。尽管结果无统计学意义，但本研究表明保留原位晶状体与更好的视觉预后相关，并且无晶状体性和假晶状体性大泡性角膜病变的临床结果无差异。
