UNASSIGNED: This prospective interventional study included 33 eyes with mature cataracts and evidence of subcapsular fluid spaces by slit lamp examination. For each patient, 20% mannitol was administered intravenously according to the bodyweight 1 h preoperatively. Under peribulbar anesthesia, a 2.2-mm main incision was made, and the anterior chamber was filled with a dispersive ophthalmic viscosurgical device. Using a bent-tip cystotome, a 2-mm curved incision was made in the center of the anterior capsule, which released subcortical fluid and was drained through compression of the posterior lip of the main incision using a spatula. Then, fine gentle milking in all quadrants around the puncture on the anterior lens capsule from the periphery toward the site of puncture using the blunt-edged spatula further assists drainage of subcortical fluid and breaks fine septa inside the lens to remove fluid from intralenticular fluid pocket collections.
UNASSIGNED: The study included 15 (45.5%) men and 18 (54.5%) women with a mean (standard deviation [SD]) of age of 63.2 (5.33) and 64.4 (6.21) years, respectively. The modified capsulorhexis technique was performed for 33 intumescent cataracts. Capsulorhexis was completed in all cases; capsulorhexis was easy in 31 (94%) eyes and difficult in 2 (6%) eyes. In the two difficult cases, radial extension occurred in one eye, and it was retrieved using the Little technique; the other case with radial tear was completed successfully using a retinal micro scissor from the other edge of the capsulorhexis until reaching an oval, continuous capsulorhexis.
UNASSIGNED: This modified capsulorhexis technique with compression on the posterior lip of the main incision and capsule milking allowed for a safe, continuous curvilinear capsulorhexis. Further comparative studies are necessary to confirm our preliminary results.
■这项前瞻性介入研究包括33只患有成熟白内障的眼睛,以及通过裂隙灯检查发现的囊膜下流体空间的证据。对于每个病人来说,术前1小时根据体重静脉内给予20%甘露醇。在球周麻醉下,做了一个2.2毫米的主切口,前房充满了一个分散的眼科黏液外科装置。用一个弯曲尖端的膀胱取样器,在前囊的中心做了一个2毫米的弯曲切口,释放皮质下液体,并通过使用刮刀压缩主切口的后唇进行引流。然后,使用钝刃刮刀在晶状体前囊穿刺周围的所有象限中从外围向穿刺部位进行细微的挤奶,进一步有助于皮质下液体的引流,并破坏晶状体内的细隔膜,以从晶状体内的液袋集合中去除液体。
■该研究包括15名(45.5%)男性和18名(54.5%)女性,平均年龄(标准差[SD])分别为63.2(5.33)和64.4(6.21)岁,分别。对33例膨胀型白内障进行了改良的撕囊技术。在所有情况下都完成了撕囊术;撕囊术在31只(94%)眼中很容易,在2只(6%)眼中很困难。在这两个困难的案例中,一只眼睛发生径向延伸,并使用Little技术将其取回;另一个放射状撕裂的病例使用视网膜微剪刀从撕囊的另一个边缘成功完成,直到达到椭圆形,连续撕囊.
■这种改良的撕囊技术对主切口后唇进行压缩,并进行胶囊挤奶,连续曲线撕囊。需要进一步的比较研究来证实我们的初步结果。
