Abstract Details

Purpose:

To evaluate presbyopia correction with a piggy-back trifocal IOL implantation in monofocal pseudophakic patients, desiring a spectacles free outcome. We included patients whose fundus could not be preoperatively evaluated (total / intumescent cataract) and patients who could experience future decrease in vision due to glaucoma or retinal pathology.

Setting:

Asociación Para Evitar la Ceguera en Mexico, Mexico City, Mexico. Hospital Del Perpetuo Socorro, Las Palmas, Gran Canaria Spain.

Methods:

A bilateral trifocal piggy-back IOL implantation was performed by 2 different surgeons, in 10 bilateral monofocal pseudophakic patients with a primary capsular bag IOL, who desire a spectacles independence. Prospective study was performed in patients with a postoperative refraction: 0.25-0.50D after their cataract was removed. All had a clear and center monofocal IOL in the capsular bag, and their far vision was from 20/25- 20/20. Among the patients included, ocular pathology with loss of contrast sensitivity was excluded. None of the trifocal IOLs implants had to be removed at 3 months postopetatively because photopic effects, refractive surprises or visual disturbances.

Results:

Bilateral presbyopia correction was achieved in 100% of the patients, with spectacles independency reading. Sulcus trifocal IOLs provided good centration and predictable refractive outcomes with high and satisfactory visual acuity. Some patients experienced transitory IOP elevation with good response to hypotensive drops and no endothelial cell lost was recorded. At 3 months postoperatively, far vision and refractive results remained stable and no undesirable photopic effects were reported.

Conclusions:

Implanting a Trifocal IOL on the sulcus (piggy-back technique) is a safe and predictable procedure, in patients desiring spectacles free reading vision. It allows implantation reversibility and less surgical trauma than primary IOL exchange.
