Summary

Piggyback intraocular lens (IOL) implantation with multifocal IOLs offers excellent vision for both near and far. This technique provides a safe and effective refractive solution for hyperopic patients needing high IOL power.

Area of Science:

  • Ophthalmology
  • Refractive Surgery

Background:

  • Piggyback intraocular lens (IOL) implantation corrects refractive errors when standard IOL powers are insufficient.
  • Combining piggyback techniques with multifocal IOLs can enhance visual acuity for distance and near vision while minimizing aberrations.

Observation:

  • The study involved 5 hyperopic patients (6 eyes) who underwent phacoemulsification and in-the-bag implantation of two foldable IOLs.
  • A silicone multifocal IOL was placed anterior to a silicone monofocal IOL in all cases.

Findings:

  • Excellent uncorrected visual acuities for both near and distance were achieved.
  • Patient satisfaction was high across all cases.
  • Two cases required IOL exchange due to inaccurate power calculations for the anteriorly placed lens.

Implications:

  • Piggyback IOL implantation using multifocal lenses is a safe and efficient refractive solution.
  • This technique offers a viable option for managing hyperopia and achieving high-quality vision.
  • Careful power calculation is crucial for optimal outcomes in piggyback multifocal IOL procedures.
