Objective:

To present cases of keratoconus patients who were unsuccessful with scleral lenses but found success with piggybacked corneal GP lenses, highlighting the significance of this approach.

Key Findings:

• Piggybacking corneal GP lenses on soft lenses can improve comfort and stability for keratoconus patients, as demonstrated in the cases.
• Daily disposable silicone hydrogel lenses are recommended for piggybacking due to their ease of use and oxygen transmissibility, which is crucial for keratoconus management.
• Some patients may adapt to corneal GP lenses alone after initial piggybacking, indicating a potential for long-term success.

Interpretation:

The use of piggyback lenses can provide a viable alternative for keratoconus patients who do not tolerate scleral lenses, enhancing their comfort and visual performance, and suggesting a need for tailored fitting strategies.

Limitations:

• The cases presented are anecdotal and may not represent broader patient outcomes; further research is needed to validate these findings.
• Individual patient responses to lens types can vary significantly, highlighting the importance of personalized fitting.

Conclusion:

Piggybacking corneal GP lenses on soft lenses is an effective strategy for improving comfort in keratoconus patients who struggle with scleral lenses, emphasizing the need for careful patient selection.
