Optical Biometry and Topography System Aladdin

Topcon Aladdin: Advanced Optical Biometry and Topography System for Precision Eye Care

The Topcon Aladdin optical biometry and topography system offers a comprehensive solution for ophthalmic professionals, combining the functionalities of an optical biometer and a full corneal topographer. With its user-friendly interface and 9-in-1 features, including optical coherence biometry, Placido topography, wavefront analysis, IOL calculation suite, pupillometry, DICOM connectivity, and the innovative RX/AL Trends Module, the Aladdin simplifies the acquisition of essential ocular measurements.

One of the standout features of the Aladdin is its ability to provide both posterior and anterior interferometry biometry results, complemented by anterior topography, Zernike analysis, and pupillometry, all in a single, fast, accurate, and easy acquisition process. The interferometer of the Aladdin offers a wealth of anterior measurements, including Central Corneal Thickness (CCT), Anterior Chamber Depth (ACD), and Lens Thickness, providing a comprehensive overview ideal for all types of cataract surgeries.

Whether performing standard cataract surgery or premium IOL implantation, the Aladdin ensures thorough screening for corneal aberrations and previous corneal refractive surgery procedures simultaneously. Its efficiency is further highlighted by requiring just one acquisition for a complete set of measurements.

The innovative RX/AL Trends Module adds another layer of functionality, allowing for the measurement and display of trends in axial length changes. This module enables practitioners to monitor change progression, chart and track refractive variations, and provide comprehensive printouts for further analysis. By combining manually entered refractive information with biometric data obtained through low-coherence interferometry, the Aladdin generates quantitative reports on the progression of changes in the eye's refractive power.

With the Aladdin, changes in critical eye parameters related to axial length, corneal curvature, anterior corneal wave front analysis, and other dimensional variations can be monitored over periods of 3, 6, and 12 months. This trend monitoring capability provides valuable insights for tracking the progression of certain eye conditions, aiding in diagnosis, treatment planning, and ongoing patient care.

The Topcon Aladdin optical biometry and topography system goes beyond standard measurements, offering specialized features for post-refractive IOL calculations and personalized cataract surgery planning. For eyes that have undergone refractive surgery such as RK, PRK, Lasik, Lasek, LK, and PTK, where spherical aberrations may deviate from standard values, the Aladdin provides on-board Barrett True-K, True-K Toric, Camellin-Calossi, and Shammas No-history formulae. These tools enable precise calculations for post-refractive IOL selection, ensuring optimal visual outcomes.

Customizability is a key aspect of the Aladdin's functionality, with a full database that can be upgraded and tailored to individual surgeon preferences. Surgeons can manually adjust the A-constant for each IOL, enhancing accuracy with every cataract surgery performed. Favorite IOLs can be pre-defined and programmed, streamlining the selection process and personalizing patient care.

The Aladdin's keratometry and topography capabilities provide comprehensive corneal assessment beyond standard K-values. Full corneal topography detects both regular and irregular astigmatism, crucial for toric IOL surgery planning. The placido rings of the Aladdin ensure extremely accurate keratometry measurements, with features like axial and tangential maps, absolute and normalized scales, and customizable zones for detailed analysis.

Pupillometry is another essential function of the Aladdin, assisting in evaluating eyes for multifocal IOL implantation or refractive surgery. Dynamic pupillometry screening assesses pupil response in different lighting conditions, ensuring accurate diagnosis and exclusion of cases with extreme pupil characteristics.

Aberrometry analysis using Zernike analysis provides detailed insights into optical aberrations, including astigmatism, spherical aberrations, higher-order aberrations, and coma across various pupil sizes. This information is crucial for optimizing visual outcomes and refining treatment plans.

The Aladdin's low-coherence interferometry system delivers precise axial length measurements, penetrating even dense cataracts with high signal-to-noise ratio. These measurements can be performed on normal eyes, as well as on aphakic, pseudo-aphakic, and silicone oil-filled eyes, ensuring accuracy across diverse patient populations.

Anterior biometry with the Aladdin encompasses measurements of central corneal thickness, anterior chamber depth, and crystalline lens thickness, providing essential data for cataract surgery planning. Interferometry ensures high precision and reproducibility, with all measurements graphically displayed for easy visualization.

Additionally, the Aladdin automatically measures white-to-white dimension, a crucial parameter for intraocular lens selection in highly myopic eyes, further enhancing reliability and accuracy in cataract surgery planning.
