Collamer lenses for accommodative ET
Reviewed by Fiona Rowe

Posterior chamber phakic IOL implantation was used to treat patients with accommodative esotropia (ET) with the goal of eliminating hyperopia and producing orthophoria. Three patients (six eyes) aged 18-22 years had an average follow-up of 17 months ±6.24. The mean preoperative spherical equivalent cycloplegic refraction was 6.04D ±0.53 and postoperative refraction of 0.41D ±0.21. This was stable over the follow-up period. All three achieved orthophoria or microesophoria postoperatively. Postoperative corneal oedema occurred in one case which recovered rapidly. One patient complained of postoperative glare which reduced over time. Preliminary results show that IOL implantation for accommodative esotropia is safe, effective, predictable and stable with low incidence of postoperative complications and positive patient satisfaction. Further large scale studies are recommended.
