PIGGYBACK OR ADD-ON INTRAOCULAR LENS

Piggyback or add-on intraocular lens implantation is a lens-based procedure that improves vision after previous eye surgery. Instead of removing the original lens implant, the surgeon places a second lens inside the eye. As a result, this approach fine-tunes vision and corrects residual refractive error. Therefore, patients may achieve clearer vision without major repeat surgery.

WHAT THIS SERVICE TREATS

This procedure corrects remaining refractive error after cataract or lens surgery. For example, it treats residual nearsightedness, farsightedness, and astigmatism. In addition, it helps patients who experience less than expected visual clarity after initial surgery. Therefore, it provides a targeted solution for vision refinement.

TYPES OF ADD-ON LENSES

The surgeon selects the most suitable lens design based on patient needs and eye measurements.

1. Spherical lenses to correct nearsightedness or farsightedness
2. Toric lenses to correct astigmatism
3. Multifocal or extended depth of focus lenses to expand range of vision
4. Custom add-on lenses designed for specific visual goals

HOW THE PROCEDURE WORKS

First, the surgeon evaluates the eye and confirms the cause of residual error. Next, the surgeon creates a small incision in the eye. Then, the surgeon places the add-on lens in front of or behind the existing implant. Because the original lens remains in place, the procedure preserves prior surgical results. As a result, recovery is often faster than full lens exchange.

WHO MAY BENEFIT

This procedure benefits patients who have undergone cataract or refractive lens surgery. In addition, it suits patients who are not ideal candidates for corneal laser enhancement. Furthermore, patients seeking improved visual quality or reduced dependence on glasses may consider this option. Therefore, it offers a flexible solution for post-surgical refinement.

RECOVERY AND EXPECTED OUTCOMES

Most patients notice visual improvement within a few days. However, mild discomfort or temporary blurred vision may occur early. Over time, vision stabilizes as the eye heals. Consequently, follow-up visits allow the surgeon to monitor healing and lens position. Because healing varies, final results may differ between patients.

SAFETY AND CLINICAL CONSIDERATIONS

The surgeon performs this procedure after detailed eye examination and precise measurements. In addition, proper lens selection plays a key role in achieving good outcomes. While the procedure has a strong safety record, risks may include inflammation, pressure changes, or lens-related issues. Therefore, careful planning and follow-up care remain essential.
