SMILE (Small incision lenticule extraction) is a type of laser eye surgery that can reduce or eliminate the need for glasses or contact lenses. The surgeon reshapes the cornea - the transparent outer layer in the front of the eye that admits light to the lens. SMILE, FDA-approved in 2016, can correct only nearsightedness and astigmatism.

After numbing the eye, the surgeon makes a tiny incision in the cornea and then uses a laser to cut a disc-shaped piece of tissue under the corneal surface (called the lenticule). The surgeon removes the lenticule through the incision, allowing the cornea to assume a new shape that improves vision. The procedure takes less than 30 minutes, after which the patient can return home.

Unlike LASIK surgery, SMILE does not cause dry eyes and does not leave a corneal flap that can dislodge. Recovery takes several days, during which patients should avoid getting water in their eyes. In one research study after six months, 99 percent of patients had at least 20/40 vision, with 88 percent achieving 20/20. Patients may still wish to use corrective lenses for reading or night driving.

The procedure is for people 22 or older with healthy eyes. In rare instances, visual impairment may result. There are also risks of inflammation, halos around bright objects at night, and vision that does not improve as expected.

​Since 2018, the Association of University Professors of Ophthalmology (AUPO) has been working to create a standardized surgical curriculum for use by ophthalmology residents. The aim is to ensure that ophthalmology residents receive training in a broad and comprehensive range of basic to advanced surgical skills.

In meeting this mandate, AUPO has developed the Surgical Curriculum for Ophthalmology Residents (SCOR). It provides a definition of surgical competence and sets benchmarks of proficiency that board-certified ophthalmologists must possess. SCOR also delivers accessible educational resources that help ensure a solid base of knowledge, reduce variability, and improve patient outcomes.

The data-driven curriculum provides access to several surgical platforms and various techniques, and involves blended online and in-person learning. An example of the in-person component is an upcoming SCOR workshop at the AAO Annual Meeting in Orlando in October 2025. The workshop will focus on advanced cataract and anterior segment skills, and encompass topics such as “small pupil management with nuclear disassembly with quick chop technique” and “advanced suturing and intraocular knot tying.”

​Using cornea and refractive surgery can significantly improve your quality of life. These procedures - including LASIK and other laser-based corrections - offer a fix for various visual issues, including nearsightedness, farsightedness, and astigmatism. Advances in these procedures have maximized results, increasing their dependability and availability.

Like LASIK, corneal and refractive procedures reshape the cornea. They enable the eye to focus light through the retina, improving vision correctly. LASIK, or laser-assisted in situ keratomileusis, remains the most well-known and carried-out eye surgery. Usually resulting in instantaneous vision improvement, the operation helps many patients achieve 20/20 vision or better without the aid of glasses or contact lenses.

LASIK and related procedures have one significant advantage: fast recovery times. Most people may resume regular activities one day or two after the operation. The rapid turnaround fits most people's schedules. Additionally, the procedure is relatively quick, lasting up to 30 minutes for both eyes.

Moreover, the procedure offers long-term savings. Though the initial surgery cost may appear excessive, it usually exceeds the cost of gradually buying contact lenses and glasses over a lifetime. Many would find great value in not depending on corrective eyeglasses for convenience. Having clear eyesight when waking every morning can significantly influence daily activities and general health.

Technology and procedures have also advanced in corneal and refractive operations. For example, customized LASIK creates a thorough map of your eye using wavefront technology, enabling a more exact correction fit for your particular visual requirements. This tailored strategy can reduce the risk of side effects and even produce superior visual results.

Another vital component of these treatments is safety. Thanks to modern technologies and techniques, eye operations carry far less danger. Particularly, LASIK has a reasonable success rate with few problems. Usually transitory, most adverse effects—such as glare or dry eyes—resolve in a few weeks.

Other choices, such as photorefractive keratectomy (PRK) or tiny incision lenticule extraction (SMILE), may be advised for patients with more severe vision problems. While SMILE is a minimally invasive operation that eliminates some corneal tissue to improve vision, PRK entails removing the cornea's outer layer and then reshaping it with a laser. Each surgery has advantages and may be more appropriate based on your vision problems and corneal thickness.

Individuals benefit from consulting with an ophthalmologist to find the most suitable surgery. The appropriate action depends on visual objectives, lifestyle, and eye health. The ophthalmologist will perform tests to evaluate your eyes and guarantee that you are a good candidate for surgery.

Furthermore, the psychological advantages of better vision are impossible to ignore—usually, improved vision results in more confidence and autonomy. Once requiring glasses or contact lenses, swimming, sports, or reading becomes more fun and less taxing.

Given the developments and advantages of cornea and refractive surgery, it is obvious why these operations have become so common. Their dependability and efficiency provide a means to improve eyesight, therefore improving everyday life and general well-being. Many people find great motivation in cutting or eliminating reliance on corrective eyeglasses, whether through LASIK, PRK, or SMILE.

Cornea and refractive surgery can significantly enhance eyesight and quality of life. These surgeries appeal to people looking for better eyesight because they combine fast recovery durations, high success rates, and modern technologies.

Two age-related conditions, cataracts and presbyopia, can impact an individual's visual acuity and ability to perform daily activities. Cataracts, characterized by the opacification of the lens, induce blurred vision and a decline in light perception. Presbyopia, a natural physiological process, results in a decreased accommodative capacity of the eye, making it challenging to focus on near objects. Consequently, these conditions can impede tasks such as reading, working on computers, and performing close-up work. Intraocular lenses (IOLs) offer a safe and effective solution for restoring clear vision. Surgeons implant these lenses during cataract surgery or refractive lens exchange. IOLs act as artificial replacements for your natural lens, correcting vision issues and improving your quality of life.

There are several types of IOLs. Each has its advantages and disadvantages. The most commonly implanted lenses are monofocal IOLs. These lenses correct vision for a single distance, be it near, far, or intermediate. For example, if you don't mind wearing reading glasses for close-up tasks like reading, monofocal IOLs to correct far-distance vision can be a great option. A significant benefit of monofocal IOLs is that they don't cause night vision disturbances like halos or glare, which can be a concern for some patients.

However, if you'd like some level of clarity for intermediate tasks like using a computer without relying on glasses, enhanced monofocal IOLs might be a better choice. While offering similar distance vision correction as traditional monofocal IOLs, these enhanced lenses may provide an additional boost to your intermediate vision as well.

For those seeking a wider range of clear vision compared to standard monofocal IOLs, extended-depth-of-focus (EDOF) IOLs can be an appropriate option. These lenses offer excellent distance vision with some improvement for intermediate tasks like seeing your car dashboard or computer screen. While EDOF IOLs provide a broader range of clarity, you might still need reading glasses for tasks requiring extreme close-up focus.

Multifocal IOLs, also known as trifocal IOLs, aim to address the need for clear vision at all distances – near, far, and intermediate. Choosing this type of lens can reduce your use of glasses for daily activities. However, there is a disadvantage. Multifocal IOLs cover all distances because their structure has several focal zones. Your brain then adjusts to these zones, selecting the appropriate zone for the task at hand. While this can lead to greater spectacle independence, some patients experience side effects like halos, starbursts, and glare, especially in low-light conditions. The good news is that these side effects typically lessen over time as your brain adapts to the new lenses.

Choosing the right IOL for you requires careful consideration of your individual needs and preferences. Some key factors to discuss with your ophthalmologist include your current vision, your dependence on glasses, and your overall lifestyle.

Regarding current vision, your ophthalmologist may ask if you are nearsighted or farsighted. They will also inquire about the presence of astigmatism. Knowing your current vision profile will help your doctor determine the most suitable IOL type for correcting your specific needs.

Another factor to consider is your comfort using glasses. If you prefer minimal reliance on glasses, multifocal IOLs might be suitable. However, the doctor will explain the potential side effects, such as night glares. Discussing your tolerance for these effects with your doctor is crucial.

Your ophthalmologist will also assess your lifestyle in terms of daily activities. They will evaluate whether you prioritize clear distance vision for activities like driving or close-up vision for reading and hobbies. For instance, if driving is a major part of your daily routine, prioritizing clear distance vision might be essential.

It's important to understand the cost implications associated with different IOL options. Not all IOLs are covered by insurance. While medical insurance typically covers monofocal IOLs, advanced IOLs with features like multifocality might require an out-of-pocket expense. By having a comprehensive discussion with your ophthalmologist about these factors, you can make an informed decision about the IOL that best aligns with your vision goals and lifestyle.
