Your optometrist will make sure that you have the clearest possible vision both at distance and up close when prescribing glasses. An autorefractor or retinoscope, phoropter, and trial frames will be used to appraise the eyes.
As with spectacles prescription, your ophthalmologist should also offer you the best possible vision with laser eye treatment.
Your sight, however, may not be as clear after surgery as compared with your spectacles.
There are times when your optometrist won’t give you the prescription which gives you the clearest sight and there are a few reasons why this is so.
If your eyes have altered dramatically compared to your previous eye exam and eyeglasses, a large change in your spectacle prescription can cause dizziness, nausea, headaches, and anxiety. To alter your Rx, your optometrist may then lower it somewhere between your last and latest prescription for ease at the expense of clarity. As a consequence, you may need to modify eyeglasses over and over again because this is just a temporary prescription to what you really should be wearing.
Modest changes in your astigmatism may not be included in your eyeglass Rx if your optometrist chooses to do so. Small variations in astigmatism do not really improve vision but can cause your new specs to be distressing.
If your glasses are for near work, a starting point for your optometrist would be to optimize your vision for a working distance of 40cm. This is the standard distance for reading. Should you be using your spectacles for computer work, it should be modified fittingly to make the computer screen more comfortable as well.
When it comes to laser eye treatment, your ophthalmologist aims to completely rectify your sight, giving you the greatest clarity. An increasing prescription rather than changing your prescription to plano (no Rx) is the common cause of discomfort when using “new prescriptions” after having laser eye surgery.
You will also discover that after laser eye treatment, you still have unhampered peripheral vision. Unhindered peripheral sight can also be caused by a high Rx or small and thick-templed frames. Your peripheral sight will be the same with wearing contact lenses.
You may think this would indicate that your vision after laser eye treatment is better to your spectacle sight.
Regrettably, not everyone is contented with their vision after having laser eye surgery. Unfortunately, even if a lot of successful patients can see 20/20 after the surgery, this is not the situation for everyone.
Of those who do see 20/20, other optical factors can result in disappointments. One effect is glares and nighttime halos that happen when the pupils enlarge in the night, enlarging past the surgical area with the peripheral of the flap causing the optic symptoms.
Near sight may also not be fully corrected with presbyopia because eyeglasses may still be needed for reading even after the laser eye treatment. Because of today’s technological advances like PresbyLasik, this is becoming less of a worry already.
It’s always best to discuss with your local ophthalmologist or optometrist before proceeding with laser eye operation. They should be able to give you professional advice about the expected outcomes based on the data they gathered from your eye exams. With their guidance, you can make an informed judgment as to whether laser eye treatment is right for you or not.
