Some lenses that are engineered to exhibit very low levels of distortion may have both positive and negative distortion. This type of distortion is called moustache or wave distortion, and requires special attention to wavelength when calibrating software to remove distortion from the final image.

LASIK, or Laser-Assisted In Situ Keratomileusis, is a revolutionary vision correction procedure that has helped millions of people achieve clearer vision without glasses or contact lenses.

LASIK offers long-term savings, reducing or eliminating the need for costly contacts and glasses, which can total over $1,000 annually. Beyond the financial benefits, LASIK improves lifestyle convenience—say goodbye to foggy glasses or dry contacts.

While most patients experience minimal discomfort, it’s important to note that individual experiences may vary. Factors like pain tolerance and adherence to post-operative care can influence your comfort level.

If you experience dry eyes after LASIK surgery, contact your ophthalmologist promptly. They can evaluate your symptoms and recommend customized treatment options like prescription eyedrops, ointments, or nutritional supplements.

In the F-Theta lens system, the actual image height is designed to satisfy the relation of ?∙?, which is smaller than the ideal image height ?∙???? in a conventional camera lens system. Because the optical system cannot completely correct all the aberrations, f-Theta lens cannot fully meet the linear relationship. F-theta distortion, which describes the relative deviation of the actual image height y from ?∙?, is defined as

Thanks to advancements in technology and techniques, LASIK is designed to be a highly comfortable procedure. Here’s a breakdown:

Unlike other types of distortion which are part of the inherent properties of the lens, keystone distortion is caused by improper alignment in a lens array. As light hits each lens and is transmitted onward, rays cross, resulting in parallax and a trapezoidal image. Keystone distortion can often be avoided by careful attention to alignment when creating lens arrays, and may also be corrected in post-processing.

For a multi-element lens assembly distortion will usually be positive or negative, but it may not be linear across the image. One should also be aware that the level of distortion may change as working distance changes and is dependent on wavelength.

LASIK is a non-invasive procedure that reshapes the cornea, the clear front part of your eye. This reshaping corrects refractive errors like:

During the recovery period, it’s crucial to attend all post-operative appointments with your Schaumburg, IL LASIK surgeon and follow their instructions diligently. If you have any concerns or questions about your recovery, don’t hesitate to reach out to them.

If you struggle with glasses and contacts due to blended nearsightedness, farsightedness or astigmatism, consulting with an experienced eye care professional at TLC Laser Eye Centers will help determine the most appropriate vision correction method based on your specific needs and prescription.

Astigmatism causes blurred vision at any distance due to an irregularly shaped front surface of the eye called the cornea.   Astigmatism is different than other refractive errors in that two or more focal points are created as light travels through the cornea.

LASIK utilizes lasers to modify the eye’s curvature, effectively addressing refractive errors. Whether you have nearsightedness and astigmatism or farsightedness and astigmatism, LASIK can simultaneously correct both conditions by reshaping the cornea. While LASIK can treat high amounts of astigmatism (up to about 6 diopters) some people  may be better candidates for alternate vision correction procedures.

Dry eye syndrome is a common condition where the eyes do not produce enough tears or the tears evaporate too quickly. Symptoms include stinging, burning, light sensitivity, blurry vision, and the feeling something is in your eye. Dry eyes can impact people of all ages but more commonly affect women and those who use digital screens extensively.

Our extensive optical experience and state of the art metrology equipment allows us to test every lens which we manufacture at Shanghai Optics, and we can provide distortion curves for specific lenses upon request. Although distortion is primarily cosmetic, it remains an important quality of every lens and the level of distortion can greatly change the ease in which information is gleaned from a system or the CPU load required for post processing.

In some situations, distortion is engineered into a system. There are many reasons why a lens distortion effect may be desirable. In laser applications, f-theta lenses are chosen to introduce a certain amount of distortion into an optical system. In cameras, image creators use an effects library which includes radial distortion, barrel distortion, perspective distortion and pincushion distortion to introduce novelty effects into their images. Wide angle lenses and zoom lenses also create their own signature type of distortion.

LASIK is a highly effective vision correction procedure, but not everyone is a suitable candidate. Here are some general criteria for LASIK candidacy in Schaumburg, IL:

While the procedure itself is typically painless, you might experience some mild discomfort afterward, similar to having a small object in your eye. This is often temporary and can be managed with over-the-counter eye drops or ointments.

LensdistortionExamples

F-theta lenses (used in laser scanning systems) are usually designed to produce a certain amount of distortion (barrel distortion) so that the image height is proportional to the field angle of θ. The ideal image height of an f-theta lens can be calculated using Equation 4

Distortion correction can be done post production in a photo editor, since the amount of distortion a lens introduces can be mathematically quantified at any given point. Distortion varies with wavelength, and in situations where a narrow band of light is used it may be computed at the central wavelength.  Digital fine-tune programs are often used to provide lens correction and eliminate unwanted distortion from a final image.

Color coding for size identify easily: Color coding is an effective way that facilitates differentiation of tools based on their respective sizes.

Distortion in a simple lens is a third-order aberration which increases with the cube of the field height. Since distortion affects the image shape, its appearance is very important especially in visual systems. Generally distortion in the order of 2 to 3% is acceptable visually.

Lens distortion is a cosmetic-type optical aberration which does not decrease the amount of information in an image. It occurs when information is displaced geometrically, and while it changes the shape of an image will not result in image blur.

As with other aberrations, a lens with a larger field of view will generally exhibit a larger amount of distortion. A fisheye lens or ultra wide-angle lens produces strong visual distortion. Figure 3 shows the distortion in a fisheye lens with effective focal length of 3.0mm. Figure 4 shows a simulated image of a wide angle lens with -50% distortion.

As with other aberrations, F-theta distortion is determined by the optical design of the lens. Shanghai Optics Inc. has over 55 years of experience in design and manufacturing low distortion f-theta lenses. Fig.5 shows the F-Theta

Optical distortionmeaning

Laser-assisted in situ keratomileusis (LASIK) is a popular refractive surgery that corrects vision problems like nearsightedness and astigmatism. As with any procedure, patients considering LASIK should understand the risks, including dry eye syndrome.

During LASIK, a thin flap is created on the cornea to reshape it with a laser. This disrupts the tear film distribution and can lead to dry spots on the cornea. Most patients have no issues, but some develop mild to moderate dry eye syndrome that typically improves with time.

Individuals with astigmatism often have a cornea resembling an egg or a football more than a perfectly round ball. Despite this difference, LASIK provides a viable solution for correcting astigmatism.

LASIK prices range from $1,499-$2,499 per eye, but the cost of LASIK surgery in Schaumburg, IL can vary depending on several factors, including the specific procedure, the technology used, and the individual needs of the patient. To get an accurate estimate of the cost, we recommend scheduling a consultation at TLC Laser Eye Surgery Center near you or through our surgeon network we can confidently refer you to LasikPlus. Our friendly staff can provide you with a personalized evaluation and discuss the associated costs. We also offer affordable financing options to help make LASIK more accessible for our patients.
