Some Aspects Of Cataract Surgery San Antonio Patients Need To Understand
by John Sanders
Cataract is one of the major causes of blindness all over the world. It may be seen in newborns or in old age. When seen at birth, it is usually a consequence of drug or physical trauma to the baby during pregnancy. When seen in the elderly, on the other hand, it is considered a normal senile change. Surgery is used to remove the opacity and improve vision. If planning to have <a href="http://www.saeye.com">cataract surgery San Antonio</a> residents need to understand a number of things.
The severity varies and one or both eyes may be affected. The typical history is a gradual onset of clouded vision that progresses slowly over time. The substance that clouds vision forms within the lens but the rest of the eye is largely unaffected. Surgery is used to either remove the lens in its entirety then replace it with an artificial one or to get rid of the cataract and return the lens in its position.
The more widely practiced option is replacement using artificial lenses. The main advantage of artificial lenses is that they provide clearer vision compared to the already damaged natural ones. The technique that is employed to put them in position is known as phacoemulsification. In this technique, a surgical incision is first made on the lens which allows it to be opened. The hardened center is accessed, liquefied and suctioned.
There is a need for one to be properly prepared. Part of the preparation entails an ophthalmic examination that is done to confirm the diagnosis of cataract and its severity. Cases that are associated with mild impairment may not necessarily require surgical intervention. Infections and increased intraocular pressure may mean that the procedure be postponed until the conditions have been managed.
The operation is a minor surgical procedure that can be safely performed in an outpatient clinic. Except in rare cases, general anesthesia is not needed. What this means is that you will be awake as the operation goes on. To reduce the sensitivity of the eye being operated on, local anesthesia will be administered as eye drops or as an injection to the eye lids.
The adoption of laser techniques has contributed to better outcomes. Another major benefit of using laser is that more precise surgical incisions can be made compared to those made by the surgical knife. Bleeding and other complications are fewer when laser is used. Apart from making surgical cuts, laser beams have also replaced ultrasound probes in liquefying the hardened opacity before suctioning.
Improvements are usually noticed as early as the first day after the surgery. Maximal benefits will, however, be realized within a couple of weeks. When an artificial intraocular lens is used, glasses are usually required as well. Apart from improved visual acuity, patients will also find it easier to look directly into light or bright objects and will also be able to differentiate colors.
There are a number of complications that may arise from this surgery. Although rare, one may suffer from bleeding into the eye. Infections may also be noted if adequate antibiotics are not used. The two complications are usually quite easy to manage and rarely impact on the outcomes. The main complication seen in the long term is posterior capsule opacification (PCO). It requires surgical correction.
