PREAMBLE OF THE DESCRIPTION:
THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION AND THE MANNER IN WHICH IT IS PERFORMED

A) TECHNICAL FIELD
[001] The present invention generally relates to a medical device and particularly relates to a protective eye gear for neonates under phototherapy treatment during neonatal jaundice.
B) BACKGROUND OF INVENTION
[002] About 60% of neonates are found with clinical jaundice or hyperbilirubinemia in the first few days after birth, while the rate is 80% for those born prematurely. Phototherapy with blue-green light is the most common treatment used for clinical jaundice. Blue-green light phototherapy in visible spectrum of 430nm to 490nm wavelength, transforms bilirubin to more water-soluble isomers, which are then excreted by the body.
[003] There is a plurality of phototherapy techniques and devices used by the hospitals to address the problem. Commercially available phototherapy systems deliver light via fluorescent bulbs, halogen quartz lamps, light-emitting diodes, and fiber-optic mattresses.
[004] Exposure to such light can be harmful for the neonate’s eyes, given the fact that the eyes are not fully developed. Eye shields are therefore required during phototherapy to protect the infant’s eyes from irritation and retinal damage. Traditionally, these eye-shields are eye-patches or eye-bands that cover the eyes by packing them, resulting in forced eye closure. They create undue pressure on the neonate’s eyes, resulting in several medical problems such as corneal damage,

corneal infection and edema. Ill-fitting bands can also lead to nasal apnea, due to
slipping on to the nose.
[005] Hence, there is a need for a protective eye gear that can cover the eyes of a
neonate during a phototherapy treatment without creating discomfort and the
aforementioned problems for the neonate.
[006] The aforesaid shortcomings, disadvantages and problems are addressed
herein, by our invention, as detailed below.
C) OBJECT OF INVENTION
[007] The primary object of the present invention is to provide a non-invasive
protective eye gear to cover a neonate’s eyes and protect them from blue-green
light during phototherapy treatment for neonatal jaundice.
[008] Another objective of this invention is to provide an eye gear which prevents
forced eye closure by allowing space for easy movement of eyelids.
[009] Another objective of this invention is to allow for hygienic reuse of the gear
by the same neonate.
[0010] These and other objectives and advantages of the embodiments herein will
become readily apparent from the following detailed description taken in
conjunction with the accompanying drawings.
D) SUMMARY OF INVENTION
[0011] The various embodiments of the present invention provide a protective eye gear for neonatal phototherapy. The eye gear comprises of an eye piece and a belt.

The eye piece comprises of a pair of hollow domes connected to each other by an
adjustable nasal bridge. The belt is an adjustable strap going around the head and
connected to the eye piece through a set of push fit buttons provided on the sides of
the eye piece.
[0012] According to one embodiment of the present invention, the eye piece and
the belt are made up of flexible and opaque silicone material.
[0013] According to one embodiment of the present invention, the belt is thinner in
areas under the head to ensure comfort as the baby lies on its back and thicker near
push fit buttons to add strength.
[0014] According to another embodiment of the invention, the belt may also be in
elastic material.
[0015] According to another embodiment of the invention, the eye gear is further
adapted for eye protection in dermatology laser surgery and for any medical
procedure requiring safe and comfortable eye gear, with necessary technical
changes as per the light source in every case.
[0016] According to another embodiment of the invention, the dome is adapted to
house multiple layers of translucent silicone. Each layer is removable in nature in
such a manner that a permissible wavelength of light is controlled by the adding or
removing the silicone layers.
[0017] According to another embodiment of the invention, each layer in the dome
has different refractive index to increase the utility of the eye gear for multiple
medical procedures.

[0018] These and other aspects of the embodiments herein will be better appreciated and understood when considered in conjunction with the following description and the accompanying drawings. It should be understood, however, that the following descriptions, while indicating preferred embodiments and numerous specific details thereof, are given by way of illustration and not of limitation. Many changes and modifications may be made within the scope of the embodiments herein without departing from the spirit thereof.

Method GURU REFLECTAN

[0027] The eye gear is made up of opaque silicone which prevents the entry of blue-green light to ensure eye safety during neonatal jaundice phototherapy. [0028] The eye gear prevents compulsory shutting of eyes. Compulsory shutting of eyes can result in corneal damage and infection, edema and irritation in the eye due to pressure. The present eye gear eradicates the aforesaid problems by providing hollow domes with comfortable space for opening and closing of eyelids. [0029] The eye gear fits snugly with good resting curvature around the eyes. Flexibility and softness of silicone allows an easy adaptability to the contours of the area surrounding the eyes. The base is additionally provided with a flat rim for good resting.
[0030] The eye gear is worn over the eyes with the help of a band going around the head. The band attaches to the push fit buttons provided on the sides of the eye piece. An adjustment for size is possible on one side with multiple slits provided on the band, which ensures a good fit. A good adjustable fit prevents the eye piece from slipping on to the nose, thus acting as a deterrent to nasal apnea.
[0031] The eye gear provides a safe usage for longer time by the neonate in a hygienic way. This is achieved by the use of silicone, which can be easily cleaned by sterilizing solution or ETO (Ethylene Oxide Sterilization).
G) ADVANTAGES OF THE INVENTION
[0032] The hollow dome shape in the eye piece of our innovation allows the neonate to move the eyelids without any hindrance, which eliminates eye irritation, edema, corneal damage and corneal infections which are caused due to forced

closure of eyes. The silicone material allows cleaning of the eye gear with sterilizing solution easily available in any hospital facility. Thus, our invention, the eye gear, can be cleaned every day and re-used for the same baby up to a period of 30 days.
[0033] It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. Therefore, while the embodiments herein have been described in terms of preferred embodiments, those skilled in the art will recognize that the embodiments herein can be practiced with modification within the spirit and scope of the claims.
