Objective:
To present the surgical outcome of posterior chamber intraocular lens scleral fixation using a 27-gauge trocar-assisted transconjunctival sutureless technique in aphakic patients due to cataract surgery complications with inadequate capsular support.
Methods:
Six consecutive patients with aphakia due to cataract surgery complications with inadequate capsular bag support were operated by two surgeons. Intraocular lens scleral fixation was performed with a 27-gauge trocar-assisted transconjunctival sutureless technique. Patients were followed-up for 12 months. Preoperative and postoperative best-corrected visual acuities were assessed with Early Treatment Diabetic Retinopathy Study charts and expressed in decimals.
Results:
All patients showed statistically significant best-corrected visual acuity improvement and excellent anatomic results. Mean preoperative best-corrected visual acuity was 0.17 (range of 0.1-0.2). Mean postoperative best-corrected visual acuity was 0.84 (range of 0.63-1.00). Mean initial spherical equivalent refractive error was +11.85 (range of +9.00 to +15.00). Mean final spherical equivalent refractive error was -0.25 (range of -1.25 to +2.25). There were no postoperative complications during the whole follow-up.
Conclusion:
Fixation of a posterior chamber intraocular lens using a 27-gauge trocar-assisted transconjunctival sutureless intrascleral technique is an excellent option for aphakic patients secondary to cataract surgery complications with inadequate capsular support.
