Eye heaviness in morning after cataract surgery

Cataract surgery is the most common operation on the human body. It has a high success rate and produces satisfying results for both patients and clinicians. Some patients may experience little discomfort following cataract surgery. It might range from mild to considerable discomfort depending on the patient's sensitivity and the type of cataract removal method employed. Cataract surgery has evolved into a low-risk refractive treatment. In cataract surgery, an incision over the cornea (the front transparent region of the eye) is necessary to gain admission within the eye and access to the lens to be replaced. This incision disrupts several connections between neurons and nerves in that area of the cornea. Such incisions may create discomfort in the patient. Healing in this area can provide unusual sensations. Though superficial healing happens in 5 to 7 days, the ultimate healing reaction occurs on a cellular level for 3 months. This can also have an impact on tear secretion. If a patient already suffers from dry eyes syndrome, surgery may cause further difficulty. Although there is minimal inflammation inside the eyes following cataract surgery or other intra-ocular surgery, this inflammation might cause discomfort. Although the frequency of inflammation is relatively low with modern cataract surgery, pre-existing inflammatory conditions such as anterior uveitis, glaucoma, and dry eyes can cause further irritation and discomfort. Following cataract surgery, a few eye drops must be given. Patients with disorders such as glaucoma, for example, would need to use significantly more eye drops after cataract surgery. Because of the preservatives in the eye drops, this can cause considerable discomfort. In such cases, preservative-free drops are important, and drops should be used according to the doctor's instructions rather than according to personal preference. Patients with particular diseases, such as diabetes, Fuch's dystrophy, recurrent corneal erosion syndrome, and LSCD, may experience severe eye discomfort after cataract surgery due to unusual corneal innervation, weak corneal structure, and altered healing response.

Diabetic Retinopathy

It is microvascular changes that occur in one's retina over a period of time during which his/her sugar control is not upto the mark. How do you know if you have diabetic retinopathy(DR), well answer to that question is simple, just have to see a ophthalmologist, a retina specialist to be more specific. What should I expect during my retina consult? In case you are found to have no evidence of DR you will be asked to review at least once a year for routine retina check up. The disease has its staging and the retina specialist is the one who is experienced enough to stage the disease accurately and call for follow-up at intervals according to the stage of your DR as per global guidelines. What if I have blurring of vision in DR? If your vision is blurred due to DR diagnosed by a retina specialist then there could be 3 reasons 1. Due to Diabetic macular edema, which can be treated with a wide range of treatment option like laser, intravitreal injections or simply by instilling drops. Now the duration and frequency of treatment has to be tailored for each individual for which again the retina specialist with his experience plans. However recurrence of this edema do occur vastly because of poor control of diabetes. 2. Due to vitreous hemorrhage, tractional retinal detachments or combined detachments, in this cases retina surgery is what is recommended by retina surgeons. Again the outcome depends on control of diabetes and pre-existing state of your retina. 3. Retina itself has become ischemic with permanent degenerative changes which are irreversible can also lead to vision loss. So as you can understand that the disease is Progressive one either slow or fast depends greatly on your Diabetic control and treatment becomes more and more complicated and expensive with minimal scope of improvement. Hence regular timely follow-ups with your retina specialist is what is recommended.

Contact lenses after cataract surgery

A contact lens is a thin, curved, transparent medical device that is placed directly on the surface of the eye to correct vision or for therapeutic purposes. It serves as an alternative to eyeglasses. Contact lenses can be used to correct various vision problems, including nearsightedness (myopia), farsightedness (hyperopia), astigmatism, and even presbyopia (age-related difficulty in focusing on close objects). Contact lenses are made from various materials, including soft hydrogel materials and rigid gas-permeable materials. Soft lenses are more flexible and comfortable to wear, while rigid gas-permeable lenses allow for better oxygen flow to the cornea. There are different types of contact lenses based on their usage: Daily Wear Lenses: These are designed to be worn during the day and removed before sleeping. They are replaced daily, bi-weekly, or monthly, depending on the type. Extended Wear Lenses: These lenses are approved by eye care professionals for overnight wear. They allow more oxygen to reach the cornea, reducing the risk of certain complications. Disposable Lenses: These lenses are designed to be worn for a specific period and then discarded. They are available as daily disposables, weekly disposables, or monthly disposables. Toric Lenses: Toric lenses are used to correct astigmatism. They have different powers in different meridians of the lens. Multifocal Lenses: These lenses are used to correct presbyopia, allowing the wearer to see clearly at multiple distances. Colored Lenses: Colored contact lenses can change the appearance of the eye's color. They are available with or without prescription. It's important to note that proper care and hygiene are crucial when using contact lenses to prevent eye infections and other complications. An eye care professional, such as an optometrist or ophthalmologist, should be consulted for a thorough eye examination, prescription, and guidance on the correct use and care of contact lenses.
