无后囊的后房型人工晶体缝线固定术

本文报告３０例（３０只眼）的后房型人工晶体缝线固定植入术，平均年龄４３．５岁。１７只眼为白内障囊内摘除术后，５只眼为囊外摘除破后囊膜者，８只眼为外伤白内障。术后随访３－１８个月，矫正视力≥０．５者为２６只眼（８６．６％），比术前矫正视力略有（０．１６）。手术中并发症主要有前房出血，瞳孔变开豚玻璃体混浊加重。术后炎性反应较一般后房人工晶体植入术重。我们对手术探讨，认为前房切口与巩膜瓣相连有利于手术操     

外伤性白内障后囊破裂人工晶体植入的手术方式选择

目的探讨外伤性白内障晶体后囊不存在时,采用前房型人工晶体植入,抑或后房型人工晶体巩膜缝线固定术。方法外伤性白内障患者８６例（８６只眼）,其中前房型人工晶体（新型弹性开放襻）植入５６例,Ⅰ期植入２９例,Ⅱ期植入２７例;后房型人工晶体巩膜缝线固定（大Ｃ型襻,两根缝线睫状沟固定）３０例,Ⅰ期植入１４例,Ⅱ期植入１６例。结果术后随访１～４２个月。矫正视力≥０．５者,前房型人工晶体组４０例,占７１．４％;缝线固定组２７例,占９０．０％。矫正视力≥１．０者,前房型人工晶体组２２例,占３９．３％;缝线固定组１４例,占４６．７％。结论新型前房型人工晶体植入和后房型人工晶体巩膜缝线固定术均不失为常规后房型人工晶体植入失败的补救措施,但前房型人工晶体适用于年龄较大、眼前段（角膜、虹膜和前房角）条件较好,而眼后段（玻璃体、视网膜）条件较差者;后房型人工晶体巩膜缝线固定术则适用于年龄较小、眼前段条件较差而眼后段条件较好者。     

白内障两种类型人工晶体植入临床观察

本文对２５例（２５眼）白内障患者因各种原因后囊膜不完整而术中行睫状沟缝线固定后房型人工晶体植入（Ⅰ组）及对２０例（２１眼）术中行弹性开放襻前房型人工晶体植入（Ⅱ组）的效果进行观察，随访３～４８个月，视力在１．０以上的Ⅰ组中有３眼，占１２％，０．５～０．８有８眼，占３２％，０．１～０．４有１３眼，占５２％，０．１以下者１眼，占４％；而Ⅱ组中视力在１．０以上者有２眼，占９．５％，０．５～０．８有７眼，占３３．３％，０．１～０．４有１０眼，占４７．６％，０．１以下者２眼，占９．５％。术后并发症Ⅰ组中主要有继发性青光眼。慢性虹膜睫状体炎；Ⅱ组中主要有：１．前房出血，２．继发性青光眼，３．虹膜睫状体炎，４．人工晶体上襻脱位。结论：在白内障术中后囊破裂不能常规植入后房型人工晶体时，只要将脱出的玻璃体处理净，手术技术娴熟，植入两种人工晶体均安全可靠。

Trabeculectomy and intraocular lens implantation: a combined procedure

We present the results achieved in 26 cases of trabeculectomy combined with intraocular lens implantation after extracapsular surgery in eyes with open-angle glaucoma. Phacoemulsification was performed in nine cases, planned extracapsular cataract extraction in 17. In 23 eyes, a posterior chamber lens was implanted; in three eyes an anterior chamber lens was used because of a ruptured posterior capsule. After a follow-up period ranging from four to 29 months, the postoperative results were satisfactory in all eyes treated. The patients achieved postoperative intraocular pressure of 20 mm Hg or less. In 28% of the cases, however, additional antiglaucomatous medication is required. Given proper indications and present-day surgical techniques, this combined procedure provides effective one-time treatment for cataract and glaucoma patients as well as optimal visual rehabilitation.

Contrast sensitivity after extracapsular and intracapsular cataract extraction

Contrast sensitivity function after cataract extraction and intraocular lens implantation has been mainly correlated to the type or the material of the intraocular lens. Our purpose was to identify other possible factors, like posterior capsule, to contrast sensitivity alterations after cataract surgery, comparing patients operated for cataract by techniques that mainly differed on the posterior capsule's integrity. The intraocular lens implanted was either a posterior or an anterior chamber one, always monofocal and made of PMMA. We measured contrast sensitivity function at four spatial frequencies in two groups of operated individuals (group A and B) and in one group of healthy control individuals. Each group consisted of 42 eyes. Group A comprised eyes with intact, clear posterior capsule and posterior chamber monofocal intraocular lens. Group B comprised eyes with ruptured or removed posterior capsule and anterior chamber monofocal intraocular lens. Control group comprised healthy control eyes. A pair matched design was used to compare contrast sensitivity values among the individuals of the three groups. No statistically significant differences in contrast sensitivity values were found when group B patients were compared to healthy controls (p>0.05). Patients of group A exhibited contrast sensitivity function impairment at intermediate and high spatial frequencies when compared to patients of group B (p <0.05) and to controls (p <0.01). It seems that intact posterior capsule provides inferior visual function, in spite of relatively good visual acuity and apparently satisfactory results.

Simultaneous penetrating keratoplasty, cataract extraction and artificial lens implantation ("triple procedure") 1981-1987

Between June 1981 and March 1987, the authors performed simultaneous penetrating keratoplasty, cataract extraction, and intraocular lens implantation in 90 eyes. The main indications were Fuchs's corneal endothelial dystrophy (38 cases), corneal cicatrization (33 cases) and corneal or scleral perforation (7 cases). Extracapsular cataract extraction with posterior chamber lens implantation was performed in 82 patients. The posterior capsule ruptured in nine eyes, necessitating an anterior vitrectomy in four of them. The corneal transplant was rejected in nine eyes (10%). The mean preoperative visual acuity of 9/100 in 89 patients improved to 39/100 six months after surgery in 59 patients who were followed up and to 50/100 in the 29 patients with Fuchs's corneal dystrophy. The authors believe that in cases presenting with both cataract and medically uncontrollable corneal disease, simultaneous penetrating keratoplasty with extracapsular cataract extraction and implantation of a posterior chamber lens represents the treatment of choice.     

晶状体玻璃体切除联合硅油填充术中晶状体囊的处理

目的探讨晶状体玻璃体切除联合眼内硅油填充术中保留前囊或后囊的作用。方法用晶状体玻璃体切除联合硅油填充治疗30例30眼伴增生性玻璃体视网膜病变的视网膜脱离患者，根据白内障手术方式不同分2组。保留后囊组：13眼术前检查为非外伤性白内障行超声乳化吸出保留后囊；保留前囊组：17眼采用经睫状体平坦部晶状体切除，并保留前囊。8眼行二期后房型人工晶状体植入。结果保留后囊组：13眼均保留了完整的晶状体后囊；保留前囊组：17眼中除3眼原有晶状体前囊小破口外，14眼保留了完整的晶状体前囊。术后随访6～24月，平均9月，无1眼发生角膜变性，近期一过性高眼压3眼，8眼二期后房型人工晶状体植入位置良好。结论晶状体玻璃体切除联合硅油填充术中保留前囊或后囊可减少角膜变性、继发青光眼的发生率，并有利于二期后房型人工晶状体植入。[眼科新进展2005；25（5）：442—443]

Cataract extraction after retinal detachment surgery

Extracapsular cataract extraction (ECCE) was done in 31 eyes of 27 patients after previous retinal reattachment surgery with scleral buckling. A posterior chamber intraocular lens (IOL) was implanted in 21 eyes. No significant modifications in the cataract surgical technique were necessary. Final visual acuity was 20/40 or better in 26 eyes (84%). The complication rate was low. One patient was found to have a retinal detachment (RD) after cataract extraction that probably predated the cataract surgery. No recurrent retinal tears or detachment developed in any patients during an average 24-month follow-up period.
