What are the three types of cataracts?

What are the common types of cataracts?

The 3 main types of age-related cataract are nuclear sclerotic, posterior subcapsular and cortical. They’re grouped based on where they form in the lens, so they have slightly different symptoms, develop at different speeds, and can have varying causes.

Are there different types of eye cataracts?

There are three main types of cataracts, affecting different parts of the lens:

  • posterior subcapsular cataracts.
  • nuclear cataracts in the center of the lens.
  • cortical cataracts on the side of the lens, which appear as small streaks.

What is the most common cataract?

A nuclear cataract is the most common type of age-related cataract. It is caused by the hardening and discoloration (yellowing) of the lens. This type of cataract forms deep in the central area, or nucleus of the lens. Over time, this type of cataract changes the eye’s ability to focus.

What are the 3 cataracts causes?

Factors that increase your risk of cataracts include:

  • Increasing age.
  • Diabetes.
  • Excessive exposure to sunlight.

What is the rarest cataract?

Hyperferritinemia-cataract syndrome is an extremely rare genetic disorder characterized by the early onset of cataracts associated with persistently elevated levels of ferritin in the blood plasma. Ferritin is a protein that binds to iron and is used as an indicator of the body’s iron stores.

How many types of cataract lenses are there?

As part of cataract surgery, your natural lens will be removed and replaced with an artificial intraocular lens. There are three different types of intraocular lenses available including monofocal, toric, and presbyopic-correcting.

What is a 2+ cataract?

These cataracts can be graded on a scale of trace to 4+, with trace being barely any visible opacification. Grade 1+ is when <5% of the posterior capsule is obscured, and Grade 2+ is when approximately 30% of the capsule is obscured.

What are the grades of cataracts?

A cataract classification and grading system developed for cataract epidemiological survey was introduced. Cataractous opacities were classified into cortical, nuclear and subcapsular types. Gradings of cataract progression were divided into early (Grade I), moderate (II) and advanced (III) stages.

What is snowflake cataract?

Diabetic cataract, or “snowflake” cataract, consists of gray-white subcapsular opacities. This type of cataract is seen, in rare cases, in patients with uncontrolled diabetes mellitus.

What is a sunflower cataract?

Sunflower cataract (SC) is considered a second ophthalmic sign of WD and has been called pathognomonic for WD [8–14]. SC consists of a thin, centralized opacification that is located directly under the anterior capsule and encompasses between one-third and one-half of the anterior lens pole surface area.

What causes cataracts to grow quickly?

Trauma-related cataracts are typically the most fast-growing type of cataracts. Radiation: Radiation-related cataracts, sometimes listed under trauma-related cataracts, occur after the lens has been exposed to radiation. Exposure to high levels of radiation can result in clouded vision in as little as two years.

Can a dense cataract be removed?

Surgically, the goal for a dense cataract is to remove the lens while minimizing endothelial damage, avoiding wound burn and intraoperative complications, and minimizing postoperative inflammation, Al-Mohtaseb said. Often, patients with these types of cataracts have small pupils.

Do eyes look different after cataract surgery?

After cataract surgery, expect your vision to begin improving within a few days. Your vision may be blurry at first as your eye heals and adjusts. Colors may seem brighter after your surgery because you are looking through a new, clear lens.
