Comparison of cataracts and presbyopia, what are early cataract symptoms?
Understanding Vision Changes After Middle Age
Eye aging experienced from entering the 40s can affect overall life. At first, it is easy to think of it as just eye fatigue, but gradually you feel difficulty reading books or using smartphones, and a phenomenon occurs where objects must be held far away to be seen clearly. While this presbyopia is one of the natural aging processes, if not corrected in time, vision weakening can accelerate and daily discomfort can intensify, so appropriate responses such as checking early cataract symptoms should be done quickly.
Wearing reading glasses is the most basic method of correcting presbyopia. It can be a simple solution without surgery, but if you suffer severe discomfort or restrictions in sports activities, you can consider presbyopia LASIK surgery as an alternative. This method improves vision by shaving the cornea using laser, similar to general LASIK or LASEK, with little pain and fast recovery, resulting in high patient satisfaction. However, if cataracts are accompanied, you need to find other approaches besides presbyopia LASIK.
Various Reasons for Cataract Development
Cataracts are a disease that occurs as lens transparency decreases, mainly caused by aging but can also appear due to other factors. For this reason, regular ophthalmology examinations are emphasized. Since genetic factors can play a role, if there is a family history, more frequent examinations are recommended.
Cataract development mainly appears with age, but can also occur due to various causes such as trauma, incorrect drug use, ophthalmic diseases, diabetes, excessive exposure to ultraviolet rays, and nutritional deficiency. If the lens capsule or optic nerve tissue is injured due to trauma, the prognosis may not be good even with quick treatment, requiring special attention.
There are also cataracts due to congenital factors, which are mostly caused by genetic factors, chromosomal abnormalities, congenital metabolic disorders, and infections during the fetal period. Since it is difficult to find a clear cause in most cases, early detection and active treatment are important. Considering these various causes of onset, a customized treatment plan for each patient must be established.
Identifying Cataract Symptoms and Examinations
When the lens becomes cloudy and light transmission is blocked, vision becomes blurry and appears hazy. Vision loss and glare appear as main symptoms, and since these cannot be corrected with glasses, surgical treatment should be considered. Surgery is an important process that must be carefully planned through sufficient consultation with a doctor.
As the lens becomes cloudy, various visual problems can occur. Representative symptoms include seeing overlapping objects, better vision in dark places, color distinction distortion, and severe glare in bright places. Since these symptoms cause great disruption to daily life, it is desirable to identify early cataract symptoms and proceed with surgery quickly. This surgery, which restores vision by removing the cloudy lens and replacing it with an intraocular lens, used to be performed through corneal incision, but now proceeds more safely using laser technology.
Treatment Timing and Surgical Selection
In the early stage after confirming early cataract symptoms, drug treatment to delay opacity progression is possible. If this method is effective, surgery can be postponed, but when vision loss is severe and there is no improvement with drug treatment, surgery should be considered immediately when vision drops below 0.5.
Cataract surgery should usually be performed after the middle stage, and if delayed, the lens hardens making surgery difficult and increasing the risk of various complications. There is a laser surgical technique that proceeds with surgery in real-time utilizing detailed eye information obtained through three-dimensional CT imaging. This method has advantages such as fast recovery after surgery and reducing the risk of secondary infection.
Characteristics of Laser Surgical Techniques
Surgery using the Catalys system measures and proceeds precisely at the micron level using 3D OCT and laser. This increases safety and reduces side effects, and clean and accurate separation of the anterior lens capsule lowers the risk of complications.
Short incision time reduces dry eye and infection risk, and using less ultrasound energy can also reduce tissue damage. When fragmenting the lens, only the necessary parts are selected to minimize damage to the remaining parts, and the fragmentation range can be set more precisely with a micron-level grid pattern.
This method, which can also correct astigmatism, enables prediction of astigmatism correction amount, and smooth incision surfaces help improve vision quality.
Intraocular Lens Selection and Management
When early cataract symptoms are discovered and surgery is received, it usually takes 20-30 minutes, and patients recover quickly enough to go home on the day of surgery. However, if proper post-surgery care is not provided, recovery speed may slow down and the risk of side effects may increase. Therefore, careful post-surgery care is important.
Intraocular lenses are divided into monofocal and multifocal, each with its own characteristics. Monofocal intraocular lenses focus on only one distance, so wearing glasses may be necessary after surgery. On the other hand, multifocal intraocular lenses focus on multiple distances, providing clear vision without glasses, and can also correct presbyopia and vision, increasing patient satisfaction.
When choosing an intraocular lens, you should not only consider the clarity of vision, but also sufficiently consider the patient’s eye condition and lifestyle to improve both vision and quality of life. Since there are cost differences depending on the type of intraocular lens chosen when early cataract symptoms are discovered, it is important to consult with a doctor and choose the option that suits you.
Cataracts, one of the senile eye diseases, mainly occur with age. If this disease is left untreated, it can lead to blindness, so early detection and active treatment are essential. Rather than considering it as part of aging, it is important to reduce eye discomfort, maintain clear vision, and keep eyes healthy.
