Perioperative assessment for refractive cataract surgery.

Area of Science:

• Ophthalmology
• Refractive Surgery
• Optical Engineering

Background:

• Cataract surgery has evolved into lens-based refractive surgery, increasing patient expectations for visual outcomes.
• Technological advancements over the last decade have significantly improved corneal measurement capabilities for pre-operative planning.

Purpose of the Study:

• To review current technologies for corneal measurement and biometry in preparation for cataract surgery.
• To aid surgeons and practices in selecting the most appropriate diagnostic tools for optimizing intraocular lens (IOL) power calculation.

Main Methods:

• Review of available technologies including topography, tomography, keratometry, and biometry.
• Discussion of advanced measurement techniques for anterior and posterior corneal surfaces.
• Inclusion of intraoperative aberrometry and integrated cataract suites in the review.

Main Results:

• Accurate estimation of corneal power, considering both anterior and posterior surfaces, is crucial for precise IOL selection.
• New equipment enables more accurate measurement of corneal power and aberrations.
• The article evaluates various technologies to help clinicians decide which are best for their practice and patients.

Conclusions:

• Accurate pre-operative corneal assessment is vital for achieving desired refractive outcomes in modern cataract surgery.
• A range of technologies exists, and understanding their strengths is key to optimal patient care and practice efficiency.
• The review provides insights into selecting the best diagnostic tools for personalized IOL implantation.
