The use of a supplemental sulcus fixated IOL (HumanOptics Add-On IOL) to correct pseudophakic refractive errors

Area of Science:

• Ophthalmology
• Refractive Surgery
• Intraocular Lenses

Background:

• Pseudophakic refractive errors present a challenge in achieving optimal visual outcomes.
• The HumanOptics Add-On intraocular lens (IOL) offers a potential solution for secondary IOL implantation.

Purpose of the Study:

• To evaluate the safety and efficacy of piggybacking an Add-On IOL to correct pseudophakic refractive errors.
• To assess visual acuity, refractive outcomes, and ocular parameters after Add-On IOL implantation.

Main Methods:

• A prospective study included 10 eyes of 10 patients with pseudophakic refractive errors.
• Preoperative and postoperative assessments included visual acuity (UDVA, CDVA), endothelial cell count (ECC), anterior chamber depth (ACD), and contrast sensitivity.
• Patients were targeted for a refractive range of -0.50 D to +0.50 D.

Main Results:

• All patients achieved the targeted refractive outcome within -0.50 D to +0.50 D.
• Significant improvement in uncorrected distance visual acuity (UDVA) was observed (p=0.0001).
• No intraoperative or postoperative complications were reported during a mean follow-up of 10.5 months.

Conclusions:

• Piggybacking the Add-On IOL is a safe and effective method for correcting pseudophakic refractive errors.
• The procedure demonstrates reliability and good visual outcomes.
• This technique provides a viable option for managing refractive surprises after cataract surgery.
