Summary
Expert surgeons identified key limitations in current diagnostic devices for cataract surgery. A next-generation device is needed for improved intraocular lens (IOL) power prediction and presbyopia correction success.
Area of Science:
- Ophthalmology
- Medical Device Development
- Surgical Technology
Background:
- Current preoperative diagnostic devices for cataract surgery present limitations impacting intraocular lens (IOL) power prediction and presbyopia correction outcomes.
- Unmet needs exist in measurement accuracy, validation, workflow, training, and surgical planning, hindering optimal patient results.
Purpose of the Study:
- To achieve consensus on the burdens associated with current diagnostic devices.
- To define requirements for next-generation diagnostic devices for improved IOL power prediction and presbyopia correction success.
Main Methods:
- A modified Delphi process involving thirteen expert refractive cataract surgeons was employed.
- Three rounds of voting, including questionnaires and a virtual meeting, were conducted to reach consensus.
Main Results:
- Consensus was reached on 40 statements, detailing 17 current limitations and 23 potential solutions.
- Key areas for improvement include corneal measurement accuracy, IOL power prediction formulas for atypical eyes, staff training, and surgical decision-making.
Conclusions:
- The modified Delphi process successfully identified unmet needs in current preoperative diagnostic devices.
- A next-generation device is required to enhance objective and subjective outcomes for surgeons, technicians, and patients.
