In this retrospective study, we reviewed the use of penetrating keratoplasty with sutureless intrasclerally fixated intraocular lens implantation in a closed anterior chamber in patients with several corneal pathologies and aphakia.
The medical records of 6 patients, who underwent the procedure, were reviewed. In the procedure, lamellar scleral tunnels at the 2- and 8-o'clock positions were created with a microvitreoretinal blade, 1.5 mm away from the limbus. Two 27-gauge bent needles were passed, first horizontally, through these tunnels, and then vertically, which allowed them to enter the posterior chamber and to be left in position. Partial thickness trephination was made, and anterior stroma was removed where necessary. An incision was made at the 11-o'clock position, where the trephination was made, which was then extended to both sides for about 6 mm with corneal scissors. From the superior incision, the anterior haptic of a 3-piece intraocular lens was pushed through the needle at the 2-o'clock position, then the posterior haptic was pushed through the needle at the 8-o'clock position, and both haptics were removed through the sclera. Both ends were cauterized and placed into the sclera. Residual stroma was removed, and the donor graft was sutured.
At the last follow-up visit, the mean bestcorrected visual acuity was significantly increased. No serious complications were seen, with the exception of increased intraocular pressure in 3 patients.
Penetrating keratoplasty with sutureless intrasclerally fixated intraocular lens implantation can be used safely in patients with aphakia. With this technique, the globe stabilization can be maintained, and the trauma to the donor graft endothelium can be minimized.
在这项回顾性研究中,我们回顾了穿透性角膜移植联合无缝线巩膜内固定人工晶状体植入术在几种角膜病变和无晶状体患者的闭角型前房中的应用。
回顾了6例接受该手术患者的病历。手术中,使用微型玻璃体视网膜刀在距离角膜缘1.5毫米处的2点和8点位置制作巩膜板层隧道。两根27号弯针先水平穿过这些隧道,然后垂直穿过,使其进入后房并留在原位。进行部分厚度的环钻术,必要时切除前基质。在进行环钻术的11点位置做一个切口,然后用角膜剪向两侧延伸约6毫米。从上方切口将三片式人工晶状体的前襻通过2点位置的针推过,然后将后襻通过8点位置的针推过,两个襻都通过巩膜取出。两端烧灼后放入巩膜。切除残留的基质,缝合供体移植物。
在最后一次随访时,平均最佳矫正视力显著提高。除3例患者眼压升高外,未观察到严重并发症。
穿透性角膜移植联合无缝线巩膜内固定人工晶状体植入术可安全用于无晶状体患者。采用该技术可维持眼球稳定,并将对供体移植物内皮的损伤降至最低。
