Laser cataract surgery with a standard IOL is a precise treatment with minimized risks. While it provides a dramatic improvement in clarity of vision, it is important to understand that because the standard IOL is monofocal (corrects vision at one distance), you will still require corrective eyewear.
For this type of technique, Dr. Thomas Byrd uses a LenSx® femtosecond laser to create ocular incisions, prior to placing the IOL. The surgery can also address astigmatism. When Dr. Byrd performs laser cataract surgery with a standard IOL at our Detroit, MI, practice, he can customize the procedure completely for each eye. The laser also makes the removal of the old lens gentler and easier on the patient.
Laser cataract surgery often achieves more precise results, due to the ability of LenSX® technology to map the eye before the procedure. The system creates a 3D image of your eye, which Dr. Byrd uses to precisely plan a customized procedure for each eye. The doctor uses the laser to make the incision in the cornea, with up to 10 times greater accuracy than he can achieve manually with a keratome blade. The laser makes the incision in a manner that provides the greatest likelihood of self-sealing, reducing the risk of infection and need for sutures.

Dr. Byrd then uses the laser to precisely and accurately create a small opening in the capsule that holds the lens in place. Studies show that performing this procedure, called a capsulotomy, with the laser allows for more accurate positioning of the intraocular lens, which can have a significant impact on the final outcome of surgery. Using the laser also provides a lower risk of breaking the capsule.
Next, Dr. Byrd uses the laser to soften and break up the affected lens. By using the laser to soften the lens as it fragments, the doctor can perform the procedure using little or no ultrasound energy when removing the old lens. This reduces the buildup of heat, which can sometimes burn the incision, necessitating sutures. The doctor then inserts the new lens. Patients may experience recovery times similar to those following traditional cataract surgery.
Some patients may have astigmatism in addition to cataracts. Astigmatism can affect the performance of the new lens, often necessitating prescription glasses or contact lenses to maintain optimal vision both close-up and at a distance. During the laser cataract procedure, Dr. Byrd can use the image created by the LenSX® system to plan a limbal relaxing incision (LRI). Astigmatism typically results from an excessively curved corneal meridian, resulting in a shape resembling a football. The LRI involves making a tiny incision in the curved area that flattens as it heals, resulting in a rounder shape. The laser allows the doctor to make these incisions with great precision and accuracy, significantly reducing astigmatism.
