Every eye is different, which means that the iLasik procedure may not always be the best fit for patients seeking to correct their vision through a refractive procedure. Whenever this is the case, we have a number of excellent alternatives available, which allows patients to become educated and to make the best choice for their vision correction method.
Like iLASIK eye surgery, PRK (advanced surface ablation or flapless LASIK) is performed with the WaveScan Wavefront™ system and the VISX Star S4™ Excimer laser that reshapes the cornea to correct the common refractive errors myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. The main difference between the two procedures is that during the iLASIK procedure, the surgeon creates a thin flap in the epithelium, the outer layer of the cornea, which he or she gently folds back to reveal the corneal tissue beneath. The PRK procedure, on the other hand, doesn’t involve the creation of an epithelial flap. Therefore, with PRK, there is no risk of complications arising from the flap; however, it typically takes longer for the eye to heal after PRK.
As our eyes age, our close vision gradually begins to degenerate, necessitating the use of reading glasses when performing close work. This common condition is known as presbyopia. An alternative to cumbersome reading glasses or bifocals, blended vision corrects one eye for intermediate (computer) vision and the other for distance vision and the brain seamlessly blends the vision together. Since the difference between the eyes is not too drastic, depth perception is rarely affected. This can be accomplished with contact lenses, refractive laser eye surgery (iLASIK or PRK), or with Advanced Technology Cataract Surgery™.
The Visian ICL Procedure is a great option for nearsighted people in the age range of 21-45 years with low to very high correction levels (-3 to -20 Diopters). The tiny, Implantable Collamer Lens® is produced by STAAR Surgical in Monrovia, CA. It is reversible, high-definition, and it works very well. For more information from Visian, please visit www.visianinfo.com. We are excited to offer this technology and we are the only practice in a 90 mile radius of Columbia, MO to provide the ICL® procedure. The risks and benefits are very similar to modern cataract surgery and recovery is usually very quick.
Refractive Lens Exchange (RLE) is another option for our patients in their late 40’s to 60’s. During this procedure, your natural crystalline lens is “exchanged” for a high-definition, biocompatible, permanent prescription Intraocular Lens (IOL). We can now correct for Astigmatism with the AcrySof Toric IQ® IOL. If you have Astigmatism, this IOL will give you the best distance vision possible. For those patients who want to free themselves of bifocals, the AcrySof ReSTOR® multifocal IOL may be a great option. This multifocal IOL provides simultaneous vision correction for distance, intermediate and near vision. RLE is very similar to cataract surgery. We remove the crystalline lens before it turns into a cataract. Therefore, you will never need cataract surgery in the future. The risks and benefits are very similar to modern cataract surgery and recovery is usually very quick.
