A method of combined cataract extraction and trabeculectomy is described in which phacoemulsification is performed through a 3.5 mm incision with insertion of a foldable hydrogel lens. This procedure is suitable for most cases in which glaucoma and cataract are coincident. In an initial series of ten patients followed for nine months, all those without additional pathology achieved a corrected visual acuity of 20/40 or better. The maximum induced astigmatism was 0.5 diopters (D), with no change or a reduction in astigmatism in seven patients (70%). Astigmatic shift between week 1 and three months was minimal (average = 0.075 D), with little change thereafter. Intraocular pressures were controlled (< or = 21 mm Hg) without adjunctive medication in all but one of the patients at nine months. This combined procedure preserves the principal advantages of small incision phacoemulsification: low induced astigmatism, early refractive stabilization, and rapid visual rehabilitation. In addition, reducing the extent of tissue dissection may reduce the stimulus to wound healing and early filtration failure.
本文描述了一种白内障摘除联合小梁切除术的方法，即通过3.5毫米切口进行超声乳化，并植入可折叠水凝胶晶状体。该手术适用于大多数青光眼合并白内障的病例。在最初一组随访9个月的10例患者中，所有无其他病变的患者矫正视力达到20/40或更好。最大诱导散光为0.5屈光度（D），7例患者（70%）散光无变化或降低。第1周和3个月之间的散光变化最小（平均=0.075 D），此后变化不大。9个月时，除1例患者外，所有患者的眼压均在无辅助药物的情况下得到控制（≤21毫米汞柱）。这种联合手术保留了小切口超声乳化的主要优点：诱导散光低、屈光早期稳定和视力快速恢复。此外，减少组织分离范围可能会减少对伤口愈合的刺激和早期滤过失败。
