Questions about parallax glasses and corneal transplant issues?

1.
After undergoing a corneal transplant in one eye, I now have significant anisometropia: my left eye has -1100 diopters of myopia and -200 diopters of astigmatism, while my right eye has -450 diopters of myopia without astigmatism.
Is it common for someone to have such a large difference in vision? Would wearing regular glasses not be feasible and potentially cause dizziness? Besides wearing regular contact lenses, are there other options available?
2.
Additionally, I would like to ask about my left eye, which underwent a corneal transplant.
I have been wearing rigid gas permeable contact lenses, but sometimes I experience a foreign body sensation (similar to having sand in my eye) that occurs intermittently.
This discomfort can be alleviated by using eye drops or by rubbing my eye.
I am uncertain if this sensation is due to remnants of the surgical sutures that might be touching the lens.
I have tried other backup rigid contact lenses, and the same issue persists, even when I am at home without wind or dust.
The sensation is less frequent when I am not wearing lenses, although I still occasionally feel like there is something in my eye.
Can a general ophthalmology clinic address issues related to potential suture remnants, or is it necessary to go to a larger hospital that specializes in corneal transplant surgeries for this kind of problem? Thank you.

Hello:
1.
Regarding the significant disparity in your vision between both eyes, this large disparity may lead to discomfort or dizziness when wearing regular glasses.
Generally, for cases of significant disparity, contact lenses may be a better option, but it is essential to make this choice under the guidance of an ophthalmologist.
Contact lenses can provide more comprehensive visual correction and reduce the sensation of foreign objects.
If you experience discomfort while wearing regular glasses, it is advisable to discuss other possible visual correction methods with your ophthalmologist to find the most suitable solution for you.
2.
Concerning the corneal transplant in your left eye, the sensation of a foreign body you described may be related to the sutures used during the surgery or other factors.
This sensation could be caused by the contact between the contact lens and the surgical area.
General ophthalmology clinics can typically handle such situations, but since your condition may involve a specialized corneal transplant procedure, it is recommended that you seek advice from an ophthalmologist who has received relevant training.
You may contact a large local hospital or an experienced ophthalmology clinic to ensure that the physician is familiar with your medical history and can provide appropriate advice and management.

Addressing vision disparities and concerns related to corneal transplants involves a nuanced understanding of ocular health, particularly when significant differences in refractive error exist between the eyes. Your situation, where one eye has undergone a corneal transplant and has a high degree of myopia (nearsightedness) and astigmatism, while the other eye has a lower degree of myopia, presents unique challenges.

1. Vision Disparity and Glasses: The significant difference in refractive error between your two eyes (left eye: -1100 with astigmatism, right eye: -450 without astigmatism) can indeed lead to discomfort and visual confusion. This disparity is known as anisometropia. When wearing traditional glasses, the brain may struggle to fuse the images from both eyes, leading to symptoms such as dizziness, headaches, and visual discomfort. In such cases, standard glasses may not provide adequate correction and could exacerbate these symptoms.
Contact lenses, particularly rigid gas-permeable (RGP) lenses or specialized soft lenses, can be a better option as they sit directly on the eye and can provide more consistent visual input. Additionally, there are options like scleral lenses, which vault over the cornea and can provide a more stable and comfortable fit, especially for individuals with corneal irregularities or previous surgeries. It is crucial to consult with an eye care professional who specializes in contact lenses to explore these options.

2. Discomfort with Rigid Contact Lenses: The sensation of having something in your eye, akin to having sand in your eye, can be attributed to several factors. It may be related to the fit of the contact lens, dryness of the eye, or even remnants of surgical sutures from the corneal transplant. If the discomfort persists, it is essential to have a thorough examination by an eye care professional. They can assess the fit of your lenses, check for any corneal irregularities, and determine if any residual sutures are causing irritation.

General eye clinics can often address these issues, but if your situation is complex due to the history of corneal transplant, it may be beneficial to consult a specialist or a larger medical center with experience in managing post-transplant complications. They will have the necessary tools and expertise to evaluate your cornea's health and the impact of your contact lenses.

In summary, managing significant vision disparities and discomfort following a corneal transplant requires a tailored approach. It is essential to work closely with an eye care professional who understands your unique situation and can provide appropriate solutions, whether through specialized contact lenses or further evaluations of your corneal health. Regular follow-ups and open communication with your eye care provider will be key to achieving the best possible visual outcomes and comfort.
