Technology and Experience

Focal Point Vision was the first to bring Lasik to San Antonio in November of 1997.  We were the first and most experienced with a revolutionary technique for corneal transplantation called DSEK.  Focal Point Vision was the first and still only practice in South Texas with a high definition Confocan⁴™ for diagnosing corneal disorders that could make certain surgeries unsafe.  Focal Point Vision was among the first to have an anterior segment ultrasound, Visante™.  We have been among the first in South Texas to offer both implantable contact lenses (Visan ICL™ and Verisyse™).  The practice offers all three presbyopic intraocular lens implants (Crystalens™, ReSTOR™, and Rezoom™).  The practice is among the most experienced with Intacs™ for keratoconus.  Focal Point Vision offers Conductive Keratoplasty (CK) for presbyopia, farsightedness, and astigmatism correction.  For Lasik, PRK and Lasek the doctors offer the latest platforms on the Intralase, Allegretto Wave and Visx CustomVue lasers.    We just added the latest advanced corneal imaging technology, The Pentacam, enabling the highest quality of data to plan your cataract and refractive surgery.  The practice has recently installed a comprehensive electronic medical record system to improve safety, accuracy and expediency of prescriptions and correspondence to referring doctors.  Focal Point Vision continues to invest heavily into the latest technology and training,  thereby improving safety and outcomes for our patients. 

With training at among the best Ophthalmology and Corneal Fellowship programs in the country, as well as continuing education the Surgeons of Focal Point Vision are committed to providing the latest technology and techniques in the safest way possible. 

Allegreto Wave

 Operating at an unsurpassed speed of 200 pulses per second (twice the speed of the next competing laser) with a laser beam pulse diameter of less then 1mm and a Gaussian beam profile, this tiny Gaussian beam allows for a much smoother treatment bed - resulting in crisper, sharper vision. With PerfectPulse Technology the Allegretto's eye tracking system completely controls every laser pulse as it is applied to the eye – it checks the position of the eye 200 times per second and automatically adjusts all internal mirrors to place the next pulse into the right location.

How does it work? The laser system treats farsightedness by removing tissue from the outer areas of the cornea to make it steeper. It treats astigmatism by flattening the central cornea by different amounts and at different locations to correct uneven focus.

When is it used? The laser system is intended for the LASIK (Laser-Assisted in Situ Keratomileusis) treatment of patients who:

• have farsightedness up to +6.0 diopters (D) and astigmatism up to 5 D with a maximum manifest refraction spherical equivalent (MRSE) of +6.0 D,

• are 18 years of age or older, and

• have had stable eyesight for the year prior to the pre-operative examination.

What will it accomplish? Excimer laser treatment is intended to reduce or eliminate farsightedness and/or astigmatism.

Side effects may include:

• glare from bright lights,

• halos (rings around lights),

• light sensitivity,

• night driving glare, and

• visual fluctuation.
