Definitions
- the invention relates to a temporary anti-photophobia ocular device, and to a process for its preparation. Photophobia is intolerance to light.
- One of the aims of this invention is to provide an alternative to wearing glasses after cataract surgery, which provides better comfort to the patient without reducing his vision of colors and contrasts in the long term.
- Another object is to provide a device (contact lens for example) overcoming photophobia of another origin.
- the invention consists of a temporarily colored implant so that the patient adapts more easily to changing the light transmitting capacities between the natural lens - which has yellowed over time and is eliminated during surgery - and the newly implanted lens.
- the dye incorporated in the implant is characterized by light filtering capabilities in wavelengths between 400 and 575 nm. This dye is gradually released, after the placement of the implant, in the surrounding fluids. The patient is thus protected from hypersensitivity to light immediately after surgery and will gradually regain, thanks to a progressive increase in the percentage of transmission of the wavelengths previously absorbed, a optimal vision of colors and contrasts; this aspect is all the more important as the brightness is more and more sought after in the elderly and a good vision of colors and contrasts is essential for a good quality of life.
- the invention consists of a temporarily colored contact lens under the same conditions as above.
- Eyepiece devices are already permanently colored to block the blue-violet light, the Alcon AcrySof Natural implant, or the Hoya AFl (uy) implant. Their main goal is to protect the eye from macular degeneration that can be induced by high energy wavelengths, although this is controversial. They filter only the short wavelengths, and this permanently. But :
- an ocular device which makes it possible to avoid the phenomenon of photophobia, consecutive in particular to a surgical operation of the eye, the ocular device containing one or more light-absorbing chromophores in the wavelengths of 400 at 575 nm and releasable, after implantation, in the surrounding fluids in a few weeks to a few months depending on the chromophore concentration and the affinity of the chromophore for the material constituting the device.
- the ocular device is advantageously an intraocular lens made of hydrogel polymer (for example poly (hydroxyethyl methacrylate), acrylic or methacrylic copolymers, one of the monomers of which is advantageously hydroxyethyl methacrylate, hydroxyethyl methacrylate / silicone matrices and polymers based on N-vinylpyrrolidone. , etc.) ..
- hydrogel polymer for example poly (hydroxyethyl methacrylate), acrylic or methacrylic copolymers, one of the monomers of which is advantageously hydroxyethyl methacrylate, hydroxyethyl methacrylate / silicone matrices and polymers based on N-vinylpyrrolidone. , etc.
- the chromophore (s) used are, of course, chosen from non-toxic and biocompatible chromophores capable of being extracted from the ocular device by dissolution or entrainment by the surrounding biological fluids. They absorb the in the wavelengths of 400 to 575 nm and as preferred examples, mention may be made of riboflavin in aqueous solution less than or equal to 3% (w / v) and fluorescein in aqueous solution less than or equal to 0 , 6% (m / v).
- the chromophore (s) are temporarily fixed in the hydrogel polymer, either by absorption / diffusion or by covalent or ionic association depending on the nature of the chromophore concerned.
- the invention also relates to the method of preparing the ocular device, which comprises the step of placing an uncolored ocular device in an aqueous solution of the chromophore (s), protected from light, the duration of impregnation being a function of the temperature.
- a hydroxyl polymer pellet having a thickness of 0.8 mm and a diameter of 10 mm is used as starting pellet.
- FIG. 1 is the transmission spectrum of a hydrogel polymer pellet before staining
- FIGS. 2A to 2D are the transmission spectra of a hydrogel polymer pellet stained with a 1% (m / v) solution. ) of riboflavin at day 0, 1, 30 and 60 of conditioning in a solution of sodium chloride at 0.9%.
- FIGS. 3A to 3E are the transmission spectra of a hydrogel polymer pellet stained with a solution of 0.6% (w / v) fluorescein at day 0, 1, 30, 60 and 90 of soaking in a solution sodium chloride 0.9%.
- FIGS. 4A, 4B, 4C and 4D are the transmission spectra of a hydrogel polymer pellet by a 0.1% (w / v) fluorescein solution at day 0 and 45 and 60 of soaking in a solution sodium chloride 0.9%. Examples (in vitro) Example 1
- An aqueous solution of riboflavin at 1% (w / v) is prepared.
- a hydrogel polymer pellet (Benz 25UV), having a hydration rate of 25% (w / v), is packaged in the riboflavin solution for 7 days at room temperature and under cover. light.
- the pre-conditioning pellet had the transmission spectrum shown in FIG.
- the colored pellet is then packaged in a vial containing 5 ml of 0.9% (w / v) aqueous sodium chloride solution (physiological saline) at room temperature and protected from light.
- 0.9% NaCl solution is renewed every 3 days during the experiment.
- FIG. 2A gives the transmission spectrum of the colored pellet after seven days of conditioning in the riboflavin solution and there is a net absorption of wavelengths between approximately 400 and 520 nm which makes it possible to significantly reduce the quantity of light transmitted to the retina while not negating scotopic efficiency.
- FIGS. 2B, 2C, 2D correspond to the transmission spectra respectively after 1 day, 30 days and 60 days in the NaCl solution and show the gradual elimination or release of riboflavin, the polymer gradually recovering its initial properties of transmission of the light.
- An aqueous fluorescein solution of 0.6% (w / v) is prepared.
- a hydrogel polymer pellet identical to that used in Example 1, is packaged in the fluorescein solution for 7 days at ambient temperature and protected from light. After 7 days, the pellet is packaged in a vial containing 5 ml of 0.9% (w / v) aqueous NaCl solution at room temperature and protected from light. The NaCl solution is renewed every 3 days during the experiment.
- Figures 3A to 3E show the transmission spectra at days 0, 1, 30, 60 and 90 days of conditioning in the NaCl solution. Initially, the absorption is greater than 80% for wavelengths below 520 nm. It is found that the polymer gradually regains its initial light transmission capacity, however more slowly than in Example 1.
- Example 3 A 0.1% (w / v) fluorescein aqueous solution is prepared.
- a hydrogel polymer pellet identical to that used in the preceding examples is conditioned in the fluorescein solution for 7 days at room temperature and protected from light. After 7 days, the pellet is packaged in a vial containing 5 ml of 0.9% (w / v) aqueous NaCl solution at room temperature and protected from light. The NaCl solution is renewed every 3 days during the experiment.
- Figures 4A to 4D show the transmission spectra at days 0, 15, 45 and 60 of conditioning in the NaCl solution. It can be seen that the transmission spectrum at day 0 is similar to that obtained with a 0.6% fluorescein solution (example 2) (transmission slightly higher at around 400 nm when the initial concentration is lower).
- the polymer gradually regains its initial transmission spectrum: after 60 days of conditioning in NaCl, the percentage of transmission of the most filtered wavelengths by the chromophore is greater than 65%.
- the polymer can find its spectrum of initial transmission, after 60 days of conditioning in NaCl, the percentage of transmission of the most filtered wavelengths by the chromophore is greater than 65%.
