Empirical fitting with polycon II lenses.

Area of Science:

• Ophthalmology
• Optometry
• Contact Lens Technology

Background:

• Traditionally, rigid gas permeable (RGP) lens fitting relies on trial-and-error methods.
• Practitioners seek reliable empirical fitting protocols for RGP lenses.
• Evaluating empirical fitting for specific RGP lens designs is crucial for clinical adoption.

Purpose of the Study:

• To assess the efficacy of empirical fitting for 9.0 mm Polycon II rigid gas permeable lenses.
• To determine if empirical fitting can achieve successful outcomes comparable to traditional methods.
• To identify optimal RGP lens parameters and fitting approaches for improved patient satisfaction.

Main Methods:

• A clinical investigation was conducted to evaluate empirical fitting of 9.0 mm Polycon II lenses.
• Objective and subjective outcomes were used to assess fitting success.
• The study compared outcomes for different lens designs and fitting techniques, including a lid attachment approach.

Main Results:

• Empirical fitting of the 9.0 mm Polycon II lens showed potential for success.
• Objective and subjective data indicated that a larger 9.5 mm Polycon II design was more effective.
• Combining the larger lens design with a lid attachment approach enhanced initial patient satisfaction.

Conclusions:

• Empirical fitting of rigid gas permeable lenses is a viable option for practitioners.
• The 9.5 mm Polycon II lens design, when fitted empirically with a lid attachment, offers improved initial patient outcomes.
• Further research into empirical fitting protocols can enhance RGP lens success rates and patient experience.
