Sunkingdom Ophthalmic Ultrasound Examination Instrument can be used in ophthalmology clinical application under A(A-scan echography), P(Pachymetry) and B(B-scan echography) operation modes. A-scan echography applies to axial length measurement, including anterior chamber depth, crystal thickness, vitreous length; Pachymetry applies to corneal thickness measurement; and B-scan echography applies to ocular ultrasound imaging. The device should be operated by doctors or appropriately-trained healthcare professional and should be used in hospitals or large clinics. It is prohibited to use the device on patients with active ocular inflammatory lesions (such as acute conjunctivitis, blepharitis, keratitis, corneal ulcer, dacryocystitis etc);and this device cannot be used on fetuses.

Sunkingdom Ophthalmic Ultrasound Examination Instrument, models SK-3000A, SK-3000B, SK-3000C, SK-2000AP, SK-2000A, SK-2000P is an ultrasound imaging system intended for use in ophthalmic applications. Model SK-3000A with A, P, B probes is used to biometric measurement of axial length (including anterior chamber depth, crystal thickness and vitreous length), corneal thickness and to ocular ultrasound imaging. Model SK-3000B with A, B probes is used to biometric measurement of axial length (including anterior chamber depth, crystal thickness and vitreous length) and to ocular ultrasound imaging. Model SK-3000C with B probe is used to ocular ultrasound imaging. Model SK-2000AP with A, P probes is used to biometric measurement of axial length (including anterior chamber depth, crystal thickness and vitreous length) and corneal thickness. Model SK-2000A with A probe is used to biometric measurement of axial length (including anterior chamber depth, crystal thickness and vitreous length). Model SK-2000P with P probe is used to biometric measurement of corneal thickness. Among them, the 10 MHz A probe transmits ultrasound wave into eye tissue, and measure the duration of the acoustic pulse from the A probe to anterior chamber, lens and vitreum and back to the A probe. This mode is mainly used for biometric measurement axial length, which including anterior chamber depth, lens thickness, vitreous depth of eyes. The 10 MHz B probe transmits ultrasound wave into eye tissue, and to form a sectional echogram by means of the brightness of echogenic dots. This mode is mainly used for ocular ultrasound imaging. The 20 MHz Pachymeter probe is to get the thickness of corneal by measurement of the time interval between the anterior and posterior interface reflection waves of cornea. This mode is mainly used for biometric measurement of corneal thickness. All probes can work independently, and record patient data and connect to a video printer to print image report. It also can work with computer which has the software installed to manage patient record. This device must be used by trained and qualified medical personnel. Contraindication: Patients with active ocular inflammatory lesions (such as acute conjunctivitis, blepharitis, keratitis, corneal ulcer, dacryocystitis, iridocyclitis etc) and the fetal cannot use the device.

Sunkingdom Applanation Tonometer is a manual device intended for measurement of intraocular pressure by applanation (applying a small flat disk to the cornea) to aid in the diagnosis of glaucoma.

Sunkingdom SK-R, SJ-T, SK-Q are applanation tonometers, which are indicated for measurement of intraocular pressure (IOP). Intraocular pressure (IOP) is a very important physiological parameter and has always been an indispensable part of the diagnosis and treatment of ophthalmology, especially for glaucoma. The operation principle is based on Goldmann applanation method, which is considered as the gold standard for measuring intraocular pressure. Therefore the applanation tonometer plays an important role in the diagnosis and treatment of ophthalmic diseases. Sunkingdom series of Applanation tonometer are active medical devices powered by 3V button battery. In practice, it provides two ways to read the measured intraocular pressure value, one from the dial indicator in mmHg unit, the other from the LCD display in mmHg and KPa units. It is used in conjunction with a slit lamp, and the only difference among the SK- R, SK-T, SK-Q is the connection part. Each model differs from each other depending on the type of slit lamp to be used with it as shown in the figure below. All the other technical specifications are the same for these three models. Model SK-Q is especially for the slit lamp with a large head size that cannot be configured for SK-R. Model SK-R can be left on the slit lamp permanently. It is fixed to the microscope on a mounting base and can be rotated in front of the microscope for examination. Model SK-T is mounted on the guide plate over the slit lamp axis for measurement purposes. Components of the tonometer include applanation tonometer main body, Connection mechanical parts and screws, calibration rod, and applanation prism.
