How my life improved with Intacs for cure of keratoconus!

Keratoconus

I have struggled with Keratoconus since I was diagnosed with it as a teenager. I remember trying to cope at school and all the extra stress my condition caused. A lack of depth perception made me appear clumsy as I was always tripping or miscalculating my reach.

I could no longer enjoy reading, driving, and some of my favorite sports in the same way as before. It affected my self-esteem in general and posed that much more of a challenge in high school. In between all that, random eye pain, dry eyes, and photosensitivity were constant companions of mine. Because this degenerative eye disease is also progressive, I also face the possibility of eventually needing a corneal transplant.

The eye condition causes a deformation of the eye from structural changes that take place in the cornea. The result is a conical curve that distorts vision and causes sensitivity to light. Other than a really strange looking eyeball, Keratoconus causes dry eyes, eye, pain, a lack of depth perception, impaired vision, and photosensitivity. The condition is managed with corrective lenses like hard scleral contact lenses.

Various corrective lenses can help. Scleral contact lenses are designed to keep fluid in between the eye and the lens to become part of the lens system and even out the irregularities on the surface. This allows light to focus in order to correct vision. But these hard lenses are very difficult to fit correctly and mine have always been uncomfortable. At times it seemed the hard scleral lenses were not worth the discomfort.

A lot of people don’t understand the challenges of Keratoconus. The daily struggles seem small so that it doesn’t seem like a condition that would greatly impair the quality of life. But constant dry eyes, pain, and photosensitivity make something as simple as getting through an episode of The Office a challenge. Checking Facebook, Skyping with friends, and going to the movies can be torture.

Then I heard about intacs corneal implants in Khanna Vision Institute in Beverly Hills. Corrective lenses just were not working for me anymore. Intacs seemed to be the ideal solution. The implants, I learned, were designed to stabilize the cornea and improve the condition of Keratoconus. Best of all, intacs corneal implants could also eliminate the need for a future corneal transplant.

The Khanna Vision Institute was able to fit me with intacs implants and my life has changed for the better. They helped correct the nearsightedness and astigmatism associated with my Keratoconus to relieve the stress my eyes were under. I can now enjoy the simple things that used to be so difficult. Thanks to Khanna Vision Institute and intacs, my self-confidence has increased and I no longer dread lengthy social activities.

RK incision and CXL

Is there any problem when cxl is used for stabilizing post rk incision?
Our keratoconus surgeon notes that in the  journal of cataract and refactive surgery there is a case report by Dr. Abad which deals with this situation. A patient with rk and ak suffered from ectasia or corneal bulging. On undergoing treatment with cornea cross linkage or cxl, there was a wound gape which required corneal suture. The good news is that the wounds healed with scarring and there was improvement in vision and the shape of the cornea.

RK or radial keratotomy was developed by Fyodrov in russia. Previous techniques to stabilize the instability of these incisions include suturing and intacs. AK is arcuate keratotomy. Today this is not performed, It has evolved into the popular LRI or limbal relaxing incisions.

These reviews on cxl for keratoconus are provided to keep the people of america abreast of the latest research and trend in management of keratoconus. The best treatment for you can only be determined by a consult with a eye doctor who is a specialist in treatment and cure of keratoconus.

Can CXL help unhappy RK patients?.

Can cxl or cornea cross linking help patients with poor unstable vision with after rk or radial keratotomy?
Dr. Khanna, Beverly hills keratoconus specialist, reviewed an article by Dr. Pinalla in the november issue of cornea. Thiskeratoconusdoctor reports on the short term followup on the seven eyes of 4 patients who had unstable cornea after earlier rk. They underwent corneal cross linking or cxl. There was clinically and statistically significant improvement in vision, astigmatism and hence corneal stability.
These reviews and analysis of papers in journals are provided for educational purposes by keratoconus expert practising in california, united states. Some of these treatments are not FDA approved. It is important to participate in fda approved studies in the united states.

RK  or radial keratotomy was a procedure popular in the previous century before the advent of lasik eye surgery. Many baby boomers who had RK are suffering from the late term problem of fluctuation of effect of those corneal incisions. Principles of keratoconus treatment can be applied by a cornea specialist to stiffen up the cornea.

Safety of CXL for keratoconus surgeons

Are keratoconus surgeons safe  from exposure to uv a radiation when performing cxl?
In a recent article in the prestigious journal “cornea” dr. Shetty, shetty and shetty (S3) comment on the safety of cornea collagen crosslinkage (C3).
They studied the effect of scattered uv A radiation during cxl. The study used a spectrometer to measure the irradiance reaching the surgeon  reaching the surgeon. Their conclusion was that the amount of radiation reaching was not significant and it could be further dampened by wearing protective gown and glasses.
We only publish reviews of studies done scientifically. Anecdotal opinions and non reviewed proprietary treatment may be discussed in the keratoconus forum. If you have  a question whether a particular treatment being offered by a doctor has been reviewed by peers, feel free to ask a question. We are with you in the fight against keratoconus.

Keratoconus specialist is a eye doctor who has completed a fellowship in cornea from a prestigious fellowship and than received further training in the latest treatment modalities of treatment of keratoconus.

What is Keratoconus?

what is keratoconus is  a question frequently asked by people having symptoms of keratoconus. This question is also pondered on both by keratoconus surgeons and researchers. Infact, keratoconus ophthalmology is becoming a niche in the field. So far it has been discovered that the keratoconus eye is not normal. It is a bilateral disease, with weakness in the structure of the cornea. Genetic causes are being investigated and newer treatments based on latest scientific laboratory research are generating newer treatment for keratoconus. Therefore the prognosis of keratoconus today is better than it was a decade ago. Therefore you need to see a keratoconus doctor to learn about the latest treatments for keratoconus so that you decrease or get rid of the symptoms of keratoconus.

Measuring Cornea Cross Linkage effect

Corneal collagen crosslinking or CXL for short utilizes riboflavin and ultravilolet A(UVA) of 370 nm wavelength.In CXL the riboflavin acts as a photo-sensitizer releasing reactive oxygen particles when irradiated with the UVA. The released oxygen radicals interact with surrounding molecules to form covalent bonds. These new bonds are called crosslinks. This is evidenced by increased youngs modulus or stress strain values, increased resistance to collagenase, increase in the diameter of collagen fibers and a increase in collagen shrinking temperature. Now a new study in journal of cataract and refractive surgery postulates that scheimpflug photography may be helpful in assessing the cross linking effect. There was no increase in light scattering in the top 70 microns which corresponds to the epithelium. The superficial stroma showed pronounced scattering which decreased to zero at 240 microns depth.

As always, we provide you with the latest information on treatment of keratoconus including upcoming technologies.

Cell phones, intacs and keratoconus

A question which has been posed to us by one forum member is related to the use of cell phones. Smart phones have proliferated and we have i phone, android phones and the like. These phones may emit radiation. So logical question is can they move the newer intacs or worsen the keratoconus disease. We do not know of any study which point to this. If you analyze the pathophysiology of the disease,you will realize it is due to lack of bonding between the collagen fibrils of the cornea.Radiation has not been shown as a causative factor. Cell phones wilL therefore not have any effect. Still, lets use caution, for who knows what studies 30 years from now will show.

Labors of keratoconus patients

This labor day,lets reflect on how patients suffering from keratoconus have to live their lives. Wearing thick glasses which give headaches, glare and at best only blurry vision. Another choice till now has been the very irritating contact lenses. You ca even put lipstick on a pig, but it still remains a pig. I am referring to some attempts at putting jewels on contact lenses to make them more attractive. These bulky pieces of plastic require a lot of motivation and sel flagellation. Whether these induce rubbing and cause further deterioration of keratoconus is debatable. What is not debatable is visiting Beverly hills keratoconus expert, dr.khanna and learn more about what might be beneficial to you. Yes you can use your medical insurance for this visit.

Pain after INTACS

A dentist mentioned she was in pain after Intac surgery. So what are the causes for pain after intacs surgery. Intacs, as you may recall are small plastic segment which are implanted in tunnels created in the cornea. These tunnels are created at a predetermined depth. The thin cornea with bulging apex is typical of keratoconus. Intacs push up this weakened corneal segment to come in line with the line of sight. The pressure exerted from the intacs segment can induce tension which may be felt as pain. Studies have shown that intacs may impinge on a corneal nerve causing persistent pain. Other reasons for pain may be corneal drying, erosions or a stitch.
A proper corneal evaluation done by an intacs expert can help diagnose the cause of pain after intacs insertion procedure.
