In this lecture we are talking about blocks.

A block in Ethereum, like on the bitcoin network, has to be mined.

Let's directly deep-dive into how that works:

Currently, at the time of recording this lecture, mining still works with proof of work.

That means - somewhere on this world- ethereum nodes are competing to find the solution to

a mathematical riddle.

If this riddle is found by one node then this node can add another block to the blockchain.

Here is exactly what will happen when a node found a block:

First, the node will get a reward for finding that block.

That is currently 3 Ether.

The node is adding 3 ether to it's own coinbase or etherbase address.

Then the miner will look at the list of pending transactions.

It will sort these transactions by the gas price from high to low and include as much

transactions as it can in the block.

The gas for these transactions is also added to the balance of the miner.

Then it will also include uncles or ommers and reward them.

They are called orphans on the bitcoin blockchain and dismissed.

In Ethereum they are rewarded as well, but that's another story.

And then the whole block is sealed and pushed to the network.

And then all of the transactions are also re-done basically on all other nodes of the

network.

This makes sure that the miner node wasn't cheating and everything is working exactly

as planned.

That is called consensus.

Everybody agrees on the result.

But there are also more things happening under the hood.

The block has several properties if you are looking at a typical block explorer.

There is the difficulty for example.

The difficulty determines how difficult is it to solve that mathematical riddle.

And the difficulty is variable.

A block in Ethereum should be mined every 10-19 seconds.

If it takes less than 10 seconds, the difficulty increases.

If it takes more than 19 seconds the difficulty decreases.

The next blocks will be either easier or harder to mine.

The exact algorithm is implemented in each and every Ethereum node.

And by having consensus across the network, meaning that every node will redo all calculations

that the mining node did and therefore validate a block, it is clear that every node will

itself increase or decrease difficulty.

Well, or leave the difficulty as it is.

So here is your take away:

When you send off transactions then a mining node will include this transaction in a block.

Blocks should be created every 10-19 seconds.

If it takes longer difficulty decreases.

If it takes less than 10 seconds to mine a new block, then difficulty increases.

And every calculation is re-done across the network, which is the way consensus is reached.

How Treating Eye Bags with Filler or Surgery is Determined - Duration: 11:49.

Under eye fillers have become a popular and convenient way to help improve the appearance

of under eye bags.

Filler placement under the eyes require no surgery, and can be performed in minutes to

help camouflage under eye bags..

This procedure can be performed with minimal to no bruising.

It's important to understand that under eye filler cannot be used in all cases of

under eye bags, and that surgery is often the better option.

I'm Dr Amiya Prasad.

I'm a Board Certified Cosmetic Surgeon and Fellowship Trained Oculoplastic Surgeon.

I've been in practice in Manhattan and Long Island for over 20 years.

As a cosmetic eyelid surgery specialist, I perform a wide range eyelid procedures every

day such as eye bag removal, treatment of upper eyelid hooding, Asian double eyelid

surgery, and oculoplastic specialty procedures such as eyelid ptosis correction, orbital

and lacrimal system surgery..

I am also well known for my work with injectable fillers for the face, particularly in the

the eye area, cheeks, chin, jawline, and forehead.

Essentially, unlike physicians who cannot perform surgery, I am not limited or biased

in treating the under eye area with any modality.

Many people with under eye bags are relatively young and often hesitant to consider surgery

preferring to have the under eye area treated with filler.

While eye bags can occur and become more prominent due to age, they are mostly caused by genetics,

and can occur as early as during the teen years, and in some cases even younger.

So, what are eye bags ? Eye bags are caused by fat.

Fat normally surrounds the eyes can push forward, like a hernia.

This is why the fat that causes eye bags is referred to as herniated fat.

Fat herniation under the eyes is called lower eyelid fat prolapse.

During consultation, I look at the prominence of the fat and relationship of the herniated

fat to the surrounding bone structure.

For example, there is an area below the under eye bag referred to as the tear trough.

I look to see if the puffiness can be blended with filler in the tear trough.

Generally, I use soft tissue fillers such as Restylane or Juvederm in this area as long

as the under eye bags aren't too prominent.

It's important to understand that fillers improve the appearance of eye bags, not by

reducing projection, but by adding projection to the adjacent area.

In some situations where the bags are too prominent for optimal blending, I perform

this procedure as a short term solution for people who want to look better and will undergo

surgery later on.

If the under eye bag projection is past a certain limit, as in the case of more prominent

or severe eye bags, then adding additional volume may not blend the contour of the eye

bags, and actually add more puffiness to the area, making the eye bags look even more prominent.

When selecting a doctor, keep this in mind that many doctors who are not surgeons will

choose filler to treat all eye bags cases, which means in many situations, the filler

placement can result in bigger eye bags.

When eye bags are past a certain level of projection, fillers are not appropriate and

surgery is the treatment of choice.

This surgery is referred to as lower eyelid blepharoplasty.

There are two techniques, one is called the transcutaneous approach where an incision

is made below the eyelashes, to address the fat bags.

The other approach is referred to as the transconjunctival approach where the fat pockets are addressed

from the inside of the eyelids.

In practice, it is common for many doctors to perform the transcutaneous approach to

also remove eyelid skin in an attempt to reduce wrinkling.

In almost all cases, I strongly advise that lower eyelid skin not be removed as it can

lead to complications such as rounding of the eyes, or eye exposure from skin shortage

known as lower eyelid retraction.

Oftentimes, the inside of eyelid is exposed and irritated is due to skin removal.

This condition is referred to as ectropion.

My preferred method is a more specialized technique called transconjunctival blepharoplasty,

where no external incision is made.

I approach the fat pockets from the inside of the eyelid to sculpt the fat.

Since no external incision is made, the results look natural, as if you never had eye bags.

This method preserves the lower eyelid support structures since no skin is removed, and the

anatomy of the eyelid is not compromised by disruption of the muscular support..

When performing eyelid surgery, I most often sculpt the fat to remove the bulge, but leave

some fat behind to create a smooth contour in the lower eyelids, and prevent the lower

eyelids from looking hollow.

Lower eyelid surgery is an art, so not all surgeries are performed the same way.

Having this procedure done with no external incision allow the results to appear natural,

and preservation of fat to prevent hollowed appearance provides for optimal outcomes when

performed by experienced surgeons.

Injectable fillers placed under the eyes is routinely performed with topical anesthetic

for patient comfort.

In addition, fillers like Restylane are also contain some anesthetic.

I usually prefer instruments such as blunt-tipped cannulas instead of needles to reduce the

risk of bruising after the procedure and minimize swelling caused by repeated needle entry.

Generally there is minimal downtime and I see the patient again two weeks after the

procedure to see how the filler has settled, and if additional enhancement is needed.

In my practice, eye bag surgery through the transconjunctival method is performed with

local anesthesia, with LITE sedation for comfort.

I prefer local anesthesia with sedation for almost all my surgeries as my patients are

more comfortable and able to avoid the recovery from the side effects of general anesthesia.

Consequently, my approach results in easier recovery and fast healing from the surgery.

Surgery in my practice is performed in our own in-office surgical suite, certified by

the Joint-Commission for standards of safety and sterility.

Patients routinely go home after surgery without any difficulty..

As far as downtime, patients can return to work pretty much immediately after under eye

filler.

In fact, many patients do it over their lunch hour, and return to work afterwards.

There is the possibility of of some bruising after the procedure which typically fades

in a few days.

When performed with local anesthesia, lower eyelid surgery patients return to work in

about a week.

Interestingly, we have found that the limited bruising from lower eyelid surgery can be

comparable to the bruising seen with the use of fillers.

Oftentimes, patients have much less bruising after my performing lower eyelid surgery than

patients who've had filler procedures done elsewhere.

The techniques I've developed over my career combined with the systems for care and recovery

allow my patients to recovery from lower eyelid surgery much faster than traditional surgery.

I discuss with my patients how to look at their options from a perspective of procedure

longevity.

Softer hyaluronic acid fillers like Restylane can last 6 months to 1 year before they are

eventually and safely broken down by the body.

The benefits of lower eyelid surgery can last many years.

Once fat pockets are removed, those fat pockets don't come back.

While there is a chance that other fat around the eyes can prolapse forward the eyelid appearance

can be stable for many years.

Neither fillers or lower eyelid surgery address skin quality such as crepiness.

Supplementary procedures for eyelid skin rejuvenation treatments like laser resurfacing, wrinkle

treatment, and platelet-rich plasma may be considered to address crepey skin, pigmentation

and wrinkles.

When can you look good for an event: If you want to look good for an event, both filler

and surgery can be performed on relatively short notice.

I look at each individual situation and make recommendations based on my experience.

Filler placement is a convenient option for limited eye bags, with minimal to no recovery.

Lower eyelid surgery is a more definitive procedure that can be performed for any degree

of fat prolapse, with results as if you've never had eye bags or surgery.

Patients often choose to have filler placement under the assumption that they don't have

time for surgery recovery.

In our practice, applying modern, faster healing methods, recovery from eye bag surgery can

comparable to the time it takes for filler results to settle.

Lower eyelid blepharoplasty really brightens up the whole face with minimal surgery.

In fact, many patients who I've operated on, comment on the ease of their experience

with their procedure and state that if they had been previously aware of how easy it was,

they would have done it sooner.

I hope you found this information helpful...thank you for your question
