To evaluate incision sizes during different stages of phacoemulsification and after implantation of a foldable acrylic intraocular lens (IOL).
Private eye center, Manila, Philippines.
In this prospective observational case series, incision widths were measured before and after microcoaxial phacoemulsification (2.2 mm), after cortical removal, and after implantation of a 6.0 mm optic, foldable, single-piece aspheric hydrophobic acrylic IOL using a D cartridge and a Monarch III injector.
The incision width increased in 101 (93.5%) of the 108 eyes; the enlargement was 0.1 mm in 78 eyes (77.2%) and 0.2 mm in 23 eyes (22.8%). The final incision width was 2.3 mm in 78 eyes (72.2%), 2.2 mm in 27 eyes (25.0%), 2.1 mm in 2 eyes, and 2.4 mm in 1 eye. Enlargement occurred during phacoemulsification in 39 eyes, during cortical removal in 33 eyes, and during IOL implantation in 52 eyes; 23 eyes had more than 1 enlargement. Before IOL implantation, the incision was smaller than 2.2 mm in 76 eyes (70.4%); after IOL implantation, the incision increased to 2.3 mm in 47 eyes (61.8%). Thirty-two eyes (29.6%) had a 2.3 mm incision before IOL implantation; the incision increased further (by 0.1 mm) after IOL implantation in 1 eye.
Incision enlargement occurred at different stages of phacoemulsification, mostly during IOL implantation. More than 72% of eyes had a final incision of 2.3 mm. Beginning with a 2.3 mm incision may prevent wound tears and surface irregularities.
评估超声乳化白内障吸除术不同阶段以及折叠式丙烯酸人工晶状体（IOL）植入后的切口大小。
菲律宾马尼拉的私人眼科中心。
在这项前瞻性观察性病例系列研究中，使用 D 型卡和 Monarch III 注射器，在微同轴超声乳化白内障吸除术（2.2mm）之前和之后、皮质清除后以及植入 6.0mm 光学、折叠、单件非球面疏水性丙烯酸 IOL 后，测量切口宽度。
108 只眼中有 101 只（93.5%）切口宽度增加；78 只眼（77.2%）扩大 0.1mm，23 只眼（22.8%）扩大 0.2mm。最终切口宽度为 78 只眼（72.2%）2.3mm，27 只眼（25.0%）2.2mm，2 只眼 2.1mm，1 只眼 2.4mm。在超声乳化白内障吸除术中发生扩大的有 39 只眼，在皮质清除术中发生扩大的有 33 只眼，在 IOL 植入术中发生扩大的有 52 只眼；23 只眼有不止一次扩大。在植入 IOL 之前，76 只眼（70.4%）切口小于 2.2mm；植入 IOL 后，47 只眼（61.8%）切口增加到 2.3mm。32 只眼（29.6%）植入 IOL 前切口为 2.3mm；植入 IOL 后，1 只眼切口进一步扩大（增加 0.1mm）。
切口扩大发生在超声乳化白内障吸除术的不同阶段，大多发生在 IOL 植入术中。超过 72%的眼睛最终切口为 2.3mm。从 2.3mm 的切口开始可能会防止伤口撕裂和表面不规则。
