Three cases of a torn haptic after scleral fixation using a hydrophobic acrylic intraocular lens: Case reports

摘要

Rationale: We report 3 cases of a torn haptic after successful scleral fixation with a hydrophobic acrylic intraocular lens . Patient concerns: Patients complained of decreased visual acuity about 1 week to 1 month after scleral fixation . Diagnoses: In all 3 cases, the direction of the damaged haptic correlated with the direction of the pulling force made by the hung suture material. Observation of a cheese-wiring effect on scanning electron microscopy suggested that the haptic was cut by the suture. Interventions: Patients underwent re- scleral fixation with caution. Ouctomes: There was no complication of broken haptic after re- scleral fixation . Lessons: To avoid unexpected haptic tears, great caution is needed; surgeons should avoid applying excessive pulling force to the intraocular lens when performing scleral fixation using a hydrophobic acrylic intraocular lens .
