It features advanced imaging capabilities including panoramic, cephalometric, and CBCT imaging as well as connectivity to integration with practice management systems and third party software.
Optical coherence tomography (OCT) is useful for imaging both the anterior and posterior segments in glaucoma. Posterior segment OCT allows quantification of retinal nerve fiber layer thickness, optic nerve head parameters, and ganglion cell layer thickness. Changes in these measurements over time can help detect glaucomatous progression. Anterior segment OCT visualizes angle anatomy and structures after glaucoma surgery. OCT provides objective data but results must be interpreted carefully while considering limitations such as variability between devices and lack of representation in normative databases.
This document provides information about optical coherence tomography (OCT), laser therapy for diabetic retinopathy, and vitrectomy. It defines OCT as a non-invasive imaging tool using light waves to produce cross-sectional images of the retina. Laser therapy for diabetic retinopathy aims to stimulate the RPE pump and inhibit VEGF release by applying focal or grid laser burns. Vitrectomy surgically removes the vitreous gel through a pars plana approach using small gauge instruments in order to treat various posterior segment conditions by releasing traction and inserting tamponades.
This study evaluated the outcomes of implanting intrastromal corneal ring segments (ICRS) in 25 eyes of 20 patients with corneal ectasia after refractive surgery. Post-operatively, uncorrected distance visual acuity significantly improved from 20/185 to 20/66 on average and corrected distance visual acuity significantly improved from 20/125 to 20/40 on average. Keratometry and corneal asphericity values also significantly improved. The study found that ICRS implantation can effectively treat corneal ectasia after refractive surgery by improving vision and corneal shape.
The document discusses preoperative evaluation and measurements for cataract surgery, including biometry. It covers evaluating the general health and ocular history of the patient, performing visual acuity testing, refraction, and other objective tests. It then describes methods of measuring the eye, including A-scan biometry to determine axial length using ultrasound, and optical biometry using light waves. Factors that can influence biometry measurements and techniques like keratometry are also discussed. The document concludes by covering intraocular lens power calculation and selection, noting the importance of accurate measurements and various generation of formulas used.
Recent advances in OCT technology were discussed. New features of Cirrus HD-OCT include enhanced imaging capabilities like OCT angiography, improved anterior segment imaging, swept source technology, and enhanced visualization tools. Clinical cases were also presented to demonstrate the utility of these new technologies in evaluating and managing various retinal diseases.
The document discusses optical coherence tomography (OCT) and its role in ophthalmology. It provides details on:
- The history and development of OCT, how it works using interferometry and low coherence light, and its advantages over ultrasound.
- How OCT allows high-resolution, non-invasive cross-sectional imaging of the retina and other ocular structures.
- How OCT is used to detect and monitor various retinal pathologies like age-related macular degeneration, diabetic retinopathy, macular edema and more. Abnormal findings on OCT like fluid, exudates and neovascularization are summarized.
- The principles of different OCT technologies over time including time domain, spectral domain
Modern IOL power calculation formulas incorporate measurements of axial length, corneal power, and effective lens position. Accurate preoperative measurements of these values are important for achieving the desired postoperative refractive outcome. While axial length and corneal power are key components, evolving formulas consider additional variables to improve accuracy. Measurement techniques also continue advancing, utilizing tools like optical biometers and intraoperative aberrometry. Careful consideration of biometry method, lens placement location, and patient factors can optimize IOL power calculations.

EYESTAR 900
Diagnose, plan, predict & control
The Eyestar 900 is based on future-proof technology: swept-
source OCT. It provides the user with precise measurements,
comprehensive topography and pachymetry maps, complete
cornea-to-retina biometry and high quality, detailed cross-
sectional eye images.
Acquiring all this data simultaneously, in a fast, fully-automated
measurement process results in excellent data quality, usability
and patient comfort.
The Eyestar 900 also uses unique, patent-protected Mandala scan
technology, which is designed for highly precise data acquisition.
Unlike classic radial or line scans, that scan any point only once
(besides the apex), trajectories of the Mandala scan are aligned
in an interwoven and highly dense pattern, both in the centre and
in the periphery. This, combined with the OCT inherent motion
compensation, results in a detailed and highly precise three-
dimensional data set.
This comprehensive information set supports the eye care
specialist to accurately diagnose a patient, plan surgical proce-
dures, predict outcomes and control the intervention efficacy of
cataract, refractive and anterior chamber surgeries.
TYPICAL RADIAL SCAN UNIQUE MANDALA SCAN
5. TOPOGRAPHICAL DATA
Tear film independent topography…
Eyestar 900 provides corneal topography in compliance with Class A-
topographer standards. The maps of the Cataract Suite cover 7.5 mm and
the maps of the Anterior Chamber Suite up to 12 mm in diameter, and
provide comprehensive information of the anterior and posterior surface of
the cornea, and pachymetry. The Anterior Chamber Suite offers additional
tools like trend/progression and difference views for more detailed analysis
of the topographic data collected.
MANDALA SCAN TECHNOLOGY
Makes rescanning obsolete
Due to the highly dense Mandala scan pattern, the user can create virtual
radial scans or line scan stacks, as well as individual B-scans, any time
after the data acquisition, and at any location of the 18mm diameter OCT
scan volume previously acquired. This unique feature eliminates the need
for time-consuming rescans, if a new cross-section is required.
SWEPT-SOURCE OCT TECHNOLOGY
Quantify what you see…
The refraction-corrected B-scan OCT imaging of the anterior chamber allows
visual anatomy assessment. In addition, the software also determines the
three-dimensional lens orientation and location and displays the respective
information and numerical data in an intuitive detailed results screen, featuring
the B-scan cross-section in the direction of the maximum lens tilt.

Cataract Suite
Optimized workflow, fewer surprises
The Eyestar 900’s Cataract Suite enables acquisition of all mea-
surement data necessary for state-of-the-art cataract planning in
an optimized, fully-automated measurement workflow.
The binocular measurement is typically completed in under
40 seconds, from the time the patient is asked to look into the
device to the finalization of the measurements. In this short time,
all data useful for planning of spherical, toric, multifocal and phakic
IOL is collected.
The result overview presents all data from axial measurements
to topography maps and 16 B-scans of the anterior chamber in
an intuitive display. All data can be reviewed on detail screens.
Measurements taken include axial measurements of all eye
compartments, corneal front and back topography as well as
keratometry, B-scan imaging of the anterior chamber, including
the lens, and assessment of lens tilt and decentration, as well
as Zernike analysis and vision simulation.
7. SWEPT-SOURCE OCT TECHNOLOGY
Detailed information, excellent
outcomes
Biometry based on swept-source OCT provides the user with much more
than just axial length measurements and keratometry. Detailed information
of the cornea front and back surface have the potential to significant-
ly improve cataract planning for astigmatic and post-refractive patients.
The topography maps allow the surgeon to screen for signs of corneal pathol-
ogies, that may limit the patient’s post-cataract surgery visual potential. In
toric candidates, the symmetry and regularity of the astigmatism on the
cornea front and back are readily available, allowing a thorough judgement
of the patient’s eligibility for a premium IOL.
MORE DATA FOR EXCELLENT DIAGNOSIS & OUTCOMES
Measure, visualize & understand
Anterior chamber B-scan imaging, including the lens, and identification of
lens tilt and decentration are beneficial for patient education, particularly
when it is a question of premium toric or multifocal IOL. Vision simulation
and Zernike analysis support the surgeon to set the patients expactaion
right and helps to choos the optimum procedure.
FULLY-AUTOMATED ACQUISITION PROCESS
Precise & efficient
Fast and reliable measurement acquisition is the key to efficiently achieving
excellent outcomes. Providing a fully-automated and quick acquisition pro-
cess enables easy delegation, improved patient comfort and compliance.
Built-in tear film quality assessment leads to highly precise keratometry,
complemented by swept-source OCT based laser precision biometry, topo-
graphy, pachymetry and tomography of the entire eye.

EyeSuite IOL
The ultimate planning platform for any IOL
EyeSuite IOL features a comprehensive set of state-of-the-art
IOL calculation formulas for any IOL-type or corneal condition
in cataract surgery. It includes the latest generation calculation
methods – Hill-RBF, Barrett and Olsen – for spherical, as well as
toric, IOL calculations.
One of the key features of these methods is the use of biometry
data beyond axial length (AL) and keratometry (K). Central corneal
thickness (CCT), anterior chamber depth (ACD), lens thickness
(LT), posterior keratometry (simPK) and white-to-white (WtW)
are additional parameters that improve prediction accuracy.
Extreme and unusual eyes, in particular, will benefit from the
additional information. Toric calculations incorporate the front
and back corneal surface for increased accuracy in calculating
the IOL spherical equivalent, cylinder power and orientation. This
information is then displayed in an intuitive graphic planning tool,
enabling accurate transfer of the plan to the operating room.
For post-refractive cases, EyeSuite IOL again features a complete
set of state-of-the-art calculation methods, such as Barrett’s
True K and True K Toric, which both incorporate measurement of
the posterior cornea, the Masket formula or Shammas No-History
method.
9. HILL-RBF METHOD
Certainty
Hill-RBF is a purely data-driven IOL calculation technique incorporating
pattern recognition and sophisticated data interpolation. It features a
boundary model, informing the user of the calculation’s reliability. Hill-RBF
performs equally well on long, normal and short eyes. It clearly outperforms
second- and third-generation formulas. Paired with the Abulafia-Koch
method, Hill-RBF is available for spherical and toric IOL calculations. Unlike
static theoretical formulas, the Hill-RBF method is an ongoing project and
is continuously updated for even better overall depth of accuracy.
FEWER REFRACTIVE SURPRISES
Identify the unusual
Having B-scan swept-source OCT images of the entire anterior chamber
available at the time of measurement allows visual identification of unusual
tilt and decentration of the crystalline lens. Furthermore, it facilitates easy
monitoring of automated gate positions for the biometry measurements. All
this additional information enables further minimization of refractive surprises.
