Innovative ocular goniometer for the treatment of astigmatism

Country of Origin: Spain
Reference Number: TOES20210504001
Pubilcation Date: 2021-05-10

Summary

A spanish university and an ophthalmological center have developed a portable device with Wi-Fi technology that adds precision, speed and cost savings in the surgical treatment of astigmatism. Its function is double, on the one hand, it marks a certain axis on the surface of the eye quickly and precisely, and, on the other hand, it measures the angle at which it is located a certain mark. Desired business relationship is patent licensing.

Description

The present invention relates to the field of ophthalmology, and more specifically to a new device to replace the current ocular axis marking apparatus.
This device serves to indicate in the eye the position in which the lens has to be placed, and it achieves this in a single step, mechanically and even with the patient seated. In addition, it allows capturing images and videos for later analysis.
It essentially consists of two circular, transparent discs, one of which is at least axially stationary, in which the angles from 0º to 180º are marked, which are aligned with the angles from 0º to 180º of the patient's eye; and the other one of which is movable both angularly and axially, with a reference mark and moving rigidly connected to a marking part, impregnated with die, which is responsible for marking the eye. Not only does the device make it possible to carry out said marking in a precise and comfortable manner, it also measures the angle of toric lenses already implanted.
This new device provides a precise mapping of the desired ocular axis in the immediate phase to surgery for the treatment of astigmatism. It can also be used to measure the precise position in which the lens is placed in the postoperative period and quantify possible misalignments of the toric lens, which may be responsible for the appearance of unwanted astigmatisms after surgery. Additionally, the invention can be used to measure any axis in the anterior part of the eye for any eventuality in which said procedure is required. These characteristics are especially useful in the surgical treatment of astigmatism.
As an added value, the ocular goniometer is also useful to view the position a mark. For example, it may be used to measure which axis an intraocular toric lens is placed in and if it is shifted, since the ocular goniometer axis is centered on the patient's visual axis.
This feature, not included in any of the other devices, is useful in the management of the immediate postoperative status of patients operated with toric intraocular lenses. It is known that most of the lenses that rotate do it in the first few hours. This feature helps to detect whether the lens rotated before discharging the patient, being able to replace it if needed in practically the same surgery.
The University is looking for partners to licence this patent pending technology.

Requested Partner

Companies that want to enter into a licensing agreement or alternatively technical agreement in order to explore the new possibility in the ophthalmology sector, and secondarily to the optics sector.
It may be an added benefit for companies that manufacture and sell cataract and refractive surgery devices, as well as intraocular lenses. It could increase sales of multifocal and monofocal intraocular toric lenses and toric ICL, because it can be used to measure the precise position in which the lens is placed in the postoperative period and quantify possible misalignments of the toric lens, which are responsible for the appearance of unwanted astigmatisms after surgery.
