Description

The 27D MICROPHTHALMIC IOL by Morcher is a specialized intraocular lens meticulously designed for patients with microphthalmia. Crafted from high-quality PMMA, both the optic and haptics ensure durability and compatibility within the eye. This one-piece lens features a biconvex optic with a diameter of 5.0 mm and an overall length of 12.0 mm, tailored for precise implantation.

Optical Design

• Monofocal Spheric Lens: Provides clear vision with a dioptric range extending up to +75.0D.
• Refractive Index: 1.49, offering reliable optical performance.
• UV-Light Protection: Shields the eye without additional blue light control.

Surgical Application

Intended for use in aphakia or cataract surgeries, particularly in eyes with extreme hyperopia. The lens is suitable for bimanual phacoemulsification, with a recommended incision size of 5.2 mm. Notably, the lens is not preloaded, requiring careful handling during surgery.

Performance Insights

• Visual Acuity: Delivers satisfactory distance and near visual acuity.
• Astigmatism Stability: No significant change in keratometric astigmatism post-implantation.
• Posterior Capsular Opacification: Higher incidence compared to other IOLs, which may influence long-term clarity.
• Halo Effect: Patients may notice significant haloes around light sources, impacting night vision.

Clinical Observations

Research indicates that the 27D IOL affects corneal incision architecture, with more alterations observed compared to lower dioptric lenses like the 21D. The use of automated and preloaded delivery systems has shown to result in more regular and less damaged incisions, enhancing surgical outcomes.

This lens represents a critical tool for ophthalmic surgeons addressing complex visual needs in microphthalmic eyes, offering unique benefits and considerations for optimal patient care.
