To elucidate the incidence of intraocular pressure (IOP) elevation after intraocular lens (IOL) suture fixation for ectopia of crystalline lens or IOL.
We retrospectively reviewed the medical records of patients who underwent IOL suture fixation for lens or IOL ectopia at Kumamoto University Hospital between 1998 and 2008. If both eyes underwent IOL suture fixation, only the eye that was treated first was included. Preoperative and postoperative IOPs were collected from medical records. If IOPs of 22 mmHg or higher were continuously recorded at 2 months or more after IOL suture fixation or additional glaucoma surgeries were required, the eye was defined as the eye complicated with postoperative IOP elevation.
In total, 132 patients (132 eyes) satisfied the study criteria. The mean follow-up period was 12.8 ± 18.3 months. Seventy-one eyes (53.8%) with lens ectopia included lens subluxation (62 eyes) and complete dislocation of the lens (9 eyes) while 61 eyes (46.2%) with IOL ectopia included IOL subluxation (46 eyes) and complete dislocation of the IOL (15 eyes). Five eyes (3.8%) were defined as postoperative IOP elevation. Of twenty-three eyes (17.4%) that had undergone preoperative IOPs of 22 mm Hg or higher, 2 eyes (8.7%) were defined as postoperative IOP elevation.
Postoperative IOP elevation after IOL suture fixation for ectopia of crystalline lens or IOL lens is not a frequent complication. Even in most of eyes associated with high IOP levels, IOPs were maintained within the normal range after the IOL suture fixation, which suggests that dislocated lens or IOL induce IOP elevation.
