There is a list of compiled complications of Lasik surgery.

1. It causes dryness of the eye. Experiencing dry eye is the most frequent complication related to Lasik. Even The US Food and Drug Administration warns about permanently experiencing dry eyes.  
2. It results to visual quality loss. Some Lasik patients were reported to experience trouble seeing details in dim lights. At times, some even experience visual distortions.
3. After Lasik, the cornea isn’t capable of complete healing. It is reported to weaken one’s cornea because of damaging collagen bands which provide protection to the eye.
4. Long term consequences are associated with Lasik surgery. Lasik patients are prone to cataracts. As such, patients are more exposed to undergoing repeat cataract surgeries.
5. It isn’t advisable for patients to undergo bilateral simultaneous Lasik surgery. The surgery being performed on the same day puts the patients at risk of vision loss in both eyes.
6. After Lasik, there are more serious complications which may arise. There were several after-Lasik complications reported such as inflammation resulting in corneal haze, flap dislocation and retinal detachment. 
7. It doesn’t completely remove the need for glasses. Still, Lasik does not ensure getting rid of reading eyeglasses by the time patients reach the age of 40. As the effectiveness of Lasik decreases each year, Lasik patients are more likely to use eyeglasses again. 
8. Until now, the real result of Lasik complications is not fully determined. It was recorded that FDA allowed Lasik manufacturers not to disclose the results of clinical trials. 
9. After Lasik, treatment options are limited. Lasik treatments are permanent and unalterable.
10. There are still safer options instead of Lasik. Eyeglasses and contact lens are still the safest methods to improve vision.

At present, the Food and Drug Administration is conducting a study which aims to determine the number of patients who experience the harmful effects which Lasik Surgery may cause. It is expected to be completed by 2012. Just recently, FDA sent out warning letters to 17 Lasik surgery centers for not giving full reports on the unfavorable effects of Lasik. Because of the reported negative after-effects by some Lasik patients, FDA will undergo a series of inspections to some centers for monitoring.

The price of Lasik ranges from $1000 to $5000 today. It is rather expensive. However, there are several Lasik financing options available, which is not a common knowledge. Generally, there is a very high percentage of the number of patients satisfied with the Lasik result. You must contact an ophthalmologist if you believe you are ready and able to undergo the Lasik procedure.

However, Avastin has not received FDA approval for ophthalmic uses. Based on safety issues, Genentech also restricts the sale of Avastin to compounding pharmacies for ocular uses. Both Lucentis and Avastin are owned by this company. Since the FDA has expressed no concern about the Avastin’s off label uses for AMD, many eye doctors argue that Genentech should allow Avastin to be directly sold to both physicians and compounding pharmacies. If only physicians have access to Avastin, doctors at the American Academy of Ophthalmology protest that many lower income people will be deprived of this sight-saving drug. The fact is that Lucentis cost an average of $2,000, while Avastin only needs $150.

During the widely off-label uses of Avastin, this treatment has not been proved to be as effective as Lucentis, or even more effective. No clinical study has made a comparison between the two AMD treatments. The most concern is their price discrepancy. Even if Medicare and other health insurance plans offset parts of the Lucentis expense, it is still much more expensive than Avastin. For example, patients with Medicare may only need to pay a 20% of co-payment for Lucentis, which equals about $400.

Genentech has given explanations about its different policies of the two drugs. Genentech officials say that the high price of Lucentis comes from its special development and its considerable expense of clinical trials. Lucentis is administered in the form of smaller molecules, which are more effective in controlling abnormal blood vessels. The company also claims that they will not conduct new trials for Avastin, since Lucentis has already got FDA approval and is a promising AMD solution. The good news may be that the US government is likely to fund the comparison between Lucentis and Avastin.

While the initial use of Avastin for colon and other cancers was reported to arouse risks of stroke and heart attack, its use for macular degeneration has brought no negative side effects. Most of the doctors are positive about the Avastin’s long-term safety risks. Due to its low price, researchers encourage the use of Avastin. There are also concerns that Avastin may be unable to penetrate the eye’s retina effectively. The undergoing two-year NEI clinical trails may settle down all these controversies.
