To investigate the use of femtosecond laser cataract surgery in traumatic cataracts of different origin.
The first case developed acute traumatic cataract due to penetrating injury of the cornea and the anterior lens capsule; the second developed traumatic cataract 11 years after a penetrating corneal injury; and the third developed a "white" cataract 12 months after blunt ocular trauma. In all cases, 4.5-mm capsulorrhexis and corneal incisions were performed using a femtosecond laser system (Alcon LenSx Inc), and nucleus liquefaction with the laser was performed additionally in the second case.
In all patients, a capsulorrhexis could be created with the femtosecond laser. Preexisting radial tears were present in the first case, but the remaining anterior capsule could be cut with the laser. The second and third cases showed an intact 4.5-mm capsulorrhexis. Corneal incisions were stable in all cases, and nucleus liquefaction was possible in the second case (grade 1-2 nuclear density).
Results indicate that a femtosecond laser can be used successfully in certain instances of traumatic cataract after penetrating eye injury, even if an anterior capsule laceration is present, and also after blunt trauma resulting in "white" cataracts.
研究飞秒激光白内障手术在不同来源外伤性白内障中的应用。
第一例因角膜穿透伤和前晶状体囊破裂导致急性外伤性白内障；第二例在角膜穿透伤 11 年后发生外伤性白内障；第三例在钝器眼外伤后 12 个月发生“白色”白内障。所有病例均采用飞秒激光系统（爱尔康 LenSx 公司）行 4.5mm 撕囊和角膜切口，并在第二例中额外行激光核液化。
所有患者均能用飞秒激光行撕囊。第一例存在预先存在的放射状撕裂，但剩余的前囊可以用激光切割。第二例和第三例均显示完整的 4.5mm 撕囊。所有病例的角膜切口均稳定，第二例可进行核液化（1-2 级核密度）。
结果表明，飞秒激光可成功应用于某些穿透性眼外伤后外伤性白内障，即使存在前囊破裂，也可应用于导致“白色”白内障的钝器伤后。
