Organization: S. Fyodorov Eye Microsurgery Federal State Institution
Summary:

The purpose of the study is to evaluate the relationship between the structures of the anterior chamber, disorders of the hydrodynamics of the eye and the work of the accommodation apparatus in patients with myopia. Material and Methods. The study involved 235 patients (235 eyes) with various degrees of myopic refraction. Patients are divided into 3 observation groups depending on the degree of myopia. Group 1 consisted of 103 patients (103 eyes) with mild myopia; group 2 consisted of 92 patients (92 eyes) with moderate myopia; group 3 consisted of 40 patients (40 eyes) with high myopia. Results. It was found that 95 patients with varying degrees of myopia (40.4%) had anterior chamber depth of more than 3.6 mm. During gonioscopy, goniodisgenesis was detected: in group 1 on 6 eyes (13%); in the 2nd group on 8 eyes (25%); in the 3rd group on 11 eyes (57%). A combination of increased corneal-compensated IOP of more than 21.0 mm Hg and habitual excess accommodation voltage (PINA) was recorded in group 1 in 1 case (2.3%), in group 2 in 3 cases (9.4%); in group 3 in 6 cases (31.5%). Conclusion. In myopic refraction, there is a syndrome of stretching of the anterior segment of the eyeball, which is more pronounced in high-grade myopia and is more often accompanied by ophthalmohypertension syndrome of overstrain of accommodation.

Clinical and functional assessment of accommodation disorders at ametropy

Year: 2020, volume 16 Issue: №1 Pages: 227-231
Heading: Ophtalmology Article type: Original article
Authors: Kuznetsova O.S., Solodkova E.G., Fokin V.P., Balalin S.V.
Organization: S. Fedorov Eye Microsurgery Federal State Institution
Summary:

The purpose of the study is to evaluate major accommodation disorders in patients with ametropy. Material and Methods. Analysis of the accommodation and hydrodynamics eye state was carried out on 235 people (235 eyes) with myopia (1 group) and 52 people (52 eyes) with hyperopia. The age of patients ranged from 18 to 35 years. Results. Accommodation disorders were observed in 82% of myopia cases; they were expressed through weakness of accommodation (49.2%), habitual excess tension of accommodation (HETA) (18.6%), and combined disorders (14.2%). Accommodation disorders were observed in 86.5% of hyperopia cases, which were expressed through accommodation weakness (51.9%), combined disorders (23.1 %), and HETA(11.5%). At myopia, ophthalmic hypertension was observed in 16.4% of cases with HETA and combined accommodation disorders. Ophthalmic hypertension was detected in 5.4% of hyperopia cases against the background of accommodation weakness. Conclusion. HETA and weakness of accommodation are more often observed with an increase in myopia degree, the rigidity values of the corneoscleral membrane and corneal hysteresis decrease. Weakness of accommodation is more often observed with an increase in the hyperopia degree, the rigidity values of the corneoscleral membrane and corneal hysteresis increase.

Efect of FemtoLASIK on the condition of accomodation and vis-coelastic properties of the cornea in patients with myopic refraction

Year: 2019, volume 15 Issue: №2 Pages: 555-559
Heading: Ophtalmology Article type: Original article
Authors: Fokin V.P., Solodkova E.G., Kuznetsova O.S., Balalin S.V.
Organization: S. Fedorov Eye Microsurgery Federal State Institution, the Volgograd Branch
Summary:

The purpose is to study the efect of FemtoLASIK operation on the state of accommodation, intraocular pressure and viscoelastic properties of the cornea in patients with myopic refraction. Material and Methods. Examined 84 patients (84 eyes) with myopia degrees before and after the operation Femtolasik. Results. In patients with mild myopia after Femtolasik, there was a decrease in the coefcient of accommodation microfuctuation (CAM) by 3.6 % and an increase in the coefcient of accommodation response (CAR) by 28.6 %, in patients with moderate myopia there was a decrease in the values of CAM to 11.1 % and an increase in CAR to 30 %, in patients with myopia of high degree of CAM increased by 14.4 %, and CAR 34 %, respectively. The decrease in the values of corneal-compensated intraocular pressure (IОPcc) was statistically signifcant. In the frst group decrease IОPcc amounted to 17.1 % in the second group 17.3 %, in the third of 25.8 %. Conclusion. An improvement in the state of accommodation is observed against the background of a decrease in the indicators of corneal- compensated intraocular pressure after performing the operation FemtoLASIK.

Experience of modified procedure treatment of progressive keratoconus based on corneal collagen cross-linking with femtosecond formation of intrastromal pocket

Organization: "Eye Microsurgery" n.a. academician S. N. Fedorov, Volgograd branch
Summary:

Aim: analysis of clinical and functional results, histomorphological changes of corneas in the application of the method of corneal collagen crosslinking with the formation of a femtosecond intrastromal pocket. Material and Methods. We studied 20 patients (20 eyes) that were operated for progressive keratoconus (1-2 stage) with a peripheral zone of maximum ectasia arrangement via corneal collagen cross-linking with femtosecond formation of intrastromal pocket for introduction of a photosensitizerand local ultraviolet radiation. Results. The result was a decrease of surgery duration and reduction of the severity of pain in the early postoperative period. Conclusion. This method allows to increase the safety of the treatment of keratoconus, reducing the risk of postoperative complications.
