Treatment of keratoconus with circular keratotomy in Eye Clinic Roth Bonn

About the department

The Department of Adult and Pediatric Ophthalmology at the Eye Clinic Roth Bonn provides the full range of medical services in its area of specialization. The primary focus of the department's clinical activities is laser and microsurgical interventions on the eye apparatus. The department's doctors most often operate on patients with cataracts, glaucoma, age-related macular degeneration, retinal diseases, and vitreous pathologies. The department also successfully performs laser surgery for secondary cataracts, glaucoma, and retinal pathologies. In addition, the medical facility has impressive experience in refractive surgery and eyelid surgery. The department offers patients advanced diagnostic rooms equipped for performing optical coherence tomography (including OCT angiography), fundus autofluorescence, pachymetry, corneal topography, optical biometry, endothelial microscopy, and other tests. The optimal type of treatment is prescribed individually, based on the results of a comprehensive eye examination. The department's specialists use their experience and expertise to restore patients' vision so they can see the world in vivid colors again. The Head Physician of the department is Dr. med. Felix Roth.

A large proportion of surgical interventions performed in the department are cataract surgeries. This disease is associated with partial or complete clouding of the lens. The lens acts as an anatomical lens responsible for the refraction of light rays and their projection onto the retina. As a result of cataracts, visual acuity decreases, and if left untreated, a person faces blindness. The development of cataracts is often caused by age-related changes. If this disease is suspected, the patient undergoes a diagnosis that includes biomicroscopy of the eye using a slit lamp, examination of the fundus, intraocular pressure measurement, visual acuity assessment, and visual field testing. Conservative methods for cataracts are ineffective, so sooner or later the patient will have to decide on a surgical procedure. The best therapeutic results can be achieved by ultrasound phacoemulsification, which is considered the "gold standard" for cataract treatment throughout the world. At the first stage of the operation, the ophthalmologist makes a micro-incision measuring 1.8 mm, after which the specialist turns the clouded lens into an emulsion using ultrasound and removes it from the eye with a special suction device. At the second stage of the surgical intervention, an intraocular lens is implanted in place of the removed lens through the same micro-incision, ensuring normal refraction of light rays. The duration of the operation is 15-20 minutes. Ultrasound phacoemulsification is well tolerated.

Several months or even years after ultrasound phacoemulsification, there is a risk of developing secondary cataracts. The pathological condition provokes darkening and thickening of the lens capsule, resulting in a repeated, gradual deterioration of vision. In such situations, the department's ophthalmologists offer patients laser treatment, such as YAG laser capsulotomy. This treatment method is absolutely safe and comfortable. Laser capsulotomy is performed on an outpatient basis.

Patients with glaucoma are often operated on in the department's operating rooms. Glaucoma is a severe, progressive disease in which intraocular pressure increases and the optic nerve is affected. If the patient does not receive timely medical attention, there is a high risk of developing irreversible blindness. When examining patients with suspected glaucoma, the department's doctors use innovative 3D Heidelberg retinal tomography, which allows for highly accurate assessment of pathological changes in the optic nerve and their comparison with previous diagnostic data. The task of ophthalmologists during the treatment of glaucoma is to normalize intraocular pressure. Whenever possible, eye drops are used for this, but this treatment option is not suitable for all patients. If glaucoma cannot be controlled with medication, the department's ophthalmologists consider surgery. The medical facility performs trabeculectomy, non-penetrating deep sclerectomy, iridotomy, laser trabeculoplasty, trabeculotomy, or goniotomy (in children). All operations are performed using laser and microsurgical techniques. The attending physician determines the optimal type of surgical procedure, depending on the specific clinical situation and type of glaucoma. In complex cases of glaucoma, the department's ophthalmologists offer treatment using cyclocryothermy or laser transscleral cyclophotocoagulation.

The treatment of age-related macular degeneration complements the department's therapeutic options. This disease affects the central part of the retina (macula), which may lead to blindness. Age-related macular degeneration usually develops after age 55. Diagnosis requires a comprehensive ophthalmological examination, including visual acuity testing, the Amsler grid eye test, visual field testing, fundus examination, optical coherence tomography, and fundus fluorescein angiography. Based on the diagnostic results, the department’s specialists determine the form of age-related macular degeneration (wet or dry) and begin to develop a treatment regimen. The treatment of the wet form of age-related macular degeneration involves intravitreal injections of anti-VEGF drugs. Intravitreal injections of Eylea®, Avastin®, and Lucentis® are most commonly used. The basic course of treatment includes 3-4 injections with an interval of 4-6 weeks. To slow down the progression of the dry form of age-related macular degeneration, antioxidants, vitamins A, C, and E, lutein, zinc, and other drugs are used.
