Cataracts and retinal detachment are eye conditions that can have a significant impact on your vision, especially as you age. Although there are effective treatments available, it is important to consider several factors before undergoing procedures for both conditions. Learn more about these considerations and their implications.
Imagine suddenly experiencing flashes of light, new floaters, or even a dark shadow in your vision. It can be a terrifying experience, particularly for those who also have cataracts.
Cataracts and retinal detachment are two age-related conditions that can be treated with well-established surgical procedures, but they also carry the risk of complications, including the development of one condition as a complication of treating the other.
In this article, we will dig deeper into the causes and symptoms of these conditions, as well as important factors to consider when undergoing vitrectomy for retinal conditions and cataract surgery.
What are cataracts and their complications?
A cataract is a common eye condition that can significantly impact a person's vision. This condition affects a staggering number of people globally, with over 65 million individuals affected worldwide.1 In fact, cataracts are the leading cause of blindness globally.
In the United States, cataracts affect people of all racial and ethnic backgrounds, and they are projected to become even more prevalent in the coming years. By 2050, it's expected that the number of people with cataracts in the US will double from 24.4 million to about 50 million.2
The good news is that cataracts can be treated effectively with surgery with a high success rate - when treated timely. But if left untreated, cataracts can lead to blindness.
Despite the effectiveness of cataract surgery, there is still some risk of complications, including posterior capsule rupture, retinal tears or detachment, cystoid macular edema, endophthalmitis, and others. Fortunately, most of these complications can be treated with medication or additional surgery.
One of the serious complications of cataract surgery is retinal detachment. This occurs when the retina becomes detached from the back of the eye, leading to a loss of vision in the affected area. The incidence of retinal detachment following cataract surgery varies widely in the literature, with estimates ranging from 0.2% to 3.6%. While this complication is uncommon, it's important to be aware of the potential risks associated with cataract surgery.
What are retina detachment and vitrectomy?
Retinal detachment is a serious eye problem that can cause permanent vision loss or blindness if left untreated. It occurs when the retina, which is the light-sensitive tissue at the back of the eye, is pulled away from its normal position. Similar to cataract, age is a common risk factor for retinal detachment, but it can also be caused by eye injuries, eye surgery, and nearsightedness.
If you have retina detachment that is not extensive, you may not experience any symptoms. However, if have extensive retina detachment, you may notice sudden symptoms, such as a lot of new floaters, flashes of light in one or both eyes, or a dark shadow in your field of vision.
The symptoms of retinal detachment often come on quickly, and it's essential to seek treatment as soon as possible. Delays may lead to more parts of the retina detached, which increases the risk of permanent vision loss or blindness.
A common surgical procedure for retinal detachment is vitrectomy. This procedure is also used to treat various retina conditions, including macular hole, retinal detachment, and macular pucker.
The procedure involves removing the vitreous, which is the gel-like substance that fills the eye, along with any tissue that is on the retina. Then, air or liquid is injected into the vitreous space to help flatten the retina.
Although it is a common treatment for retinal detachment, as with any surgery, it also comes with some risks. Some complications include infection, increased rate of cataract formation, excess bleeding, high pressure in the eye, and others.
Vitrectomy for retinal detachment usually works well, especially if the detachment is caught early. After surgery, your vision may take several months to improve. In some cases, you may need a second treatment or surgery if your retina detaches again.
Should I have my cataract surgery or vitrectomy first?
If you have a vitrectomy requiring condition and cataract, there are some important factors to consider when having these surgical procedures. Depending on your specific situation, you may need to have cataract surgery before or after vitrectomy, or both procedures may be done simultaneously.
Cataract surgery first: In many cases, eye doctors may recommend having cataract surgery before vitrectomy. This can improve the clarity of the back of your eye during the vitrectomy procedure. And the calculation for the intraocular lens may be more accurate, leading to better vision after the surgery.3
If cataract surgery is first, hydrophobic acrylic intraocular lenses are preferred to silicone-based intraocular lenses, due to the possible fogging or adherence of the silicone oil to the silicone-based lenses.3
Vitrectomy then cataract surgery: If you are to have or already had vitrectomy surgery, cataracts may form or progress more quickly than they would have otherwise. This can make the cataract procedure more challenging due to weakened fibers in your eye or changes to the front part of your eye, leading to the need to adjust intraocular lens position or power.3
Combined cataract and vitrectomy surgery: Your eye doctor may also recommend that you undergo both procedures at the same time. This can be more convenient and result in a faster recovery time. However, there are also potential disadvantages to consider, including longer and more complex surgery, scheduling difficulties of two subspecialists, and additional complications, such as the reopening of the cataract wound.3
Each approach has its pros and cons. Discuss with your eye doctor for more details based on your situation.
Key takeaways
Cataracts and retinal detachment are two age-related conditions that can occur at the same time. While cataract surgery and vitrectomy procedures are well-established and effective, it's important to be aware of the potential risks and complications, such as the development of one condition as a complication of treating the other.
When undergoing cataract surgery and/or vitrectomy, it is crucial to carefully consider the sequence of the procedure based on your individual situation. Your eye doctor can provide guidance and recommendations to help you make informed decisions.
By staying informed and working closely with your healthcare team, you can take steps to safeguard your vision and for the best possible outcomes for your eye health.
