[Intraocular lenses for microincisional cataract surgery]

Area of Science:

• Ophthalmology
• Surgical Technology
• Biomedical Engineering

Background:

• Micro-incisional cataract surgery (MICS) relies on foldable or rollable intraocular lenses (IOLs) and specific injector systems.
• Current MICS techniques allow for incisions smaller than 2.0 mm.

Purpose of the Study:

• To discuss the optimization of IOLs for MICS regarding material and lens body design.
• To highlight the advantages of MICS, including reduced astigmatism and higher-order aberrations.
• To emphasize the enhanced predictability of refractive outcomes with MICS, particularly for advanced IOL designs.

Main Methods:

• Review of current micro-incisional cataract surgery techniques.
• Analysis of intraocular lens (IOL) design and material requirements for small incisions.
• Comparison of MICS outcomes with standard cataract surgery procedures.

Main Results:

• Micro-incisional cataract surgery (MICS) enables implantation through incisions <2.0 mm.
• MICS results in minimal induced astigmatism and fewer higher-order aberrations compared to standard procedures.
• MICS offers superior predictability for postoperative refractive results.

Conclusions:

• IOLs for MICS require specific optimization in material and lens body design for small incision implantation.
• Micro-incisional cataract surgery (MICS) provides significant advantages in optical quality and refractive predictability.
• MICS is particularly beneficial for the implantation of advanced optic designs like aspheric, toric, and multifocal IOLs.
